How to issue a time resynchronization in Windows - cmd/batch

 Hello again, I'm back. I found some spare time to add some updated tricks concerning technology, and general tips for Windows or GNU/Linux. :)

I've been having some problems with the time synchronization in Windows 7, which required more often synchronization. So after some googling around, I came up with this little batch commands:
echo Current date/time: %date%_%time%
%windir%\system32\sc.exe start w32time task_started
%windir%\system32\w32tm.exe /resync
echo Fixed date/time: %date%_%time%
pause

Save it as a .bat file and run it as an administrator (right-click on file > Run as administrator).
It's nothing much, pretty dirty scripting I confess, but it does get the job done, at least in my case. I hope it will help someone else too.

See ya!

Icon 'gtk-close' not present in theme

I recently started to use screenlets again, especially FreeMeteo for weather forecast. But on ubuntu 12.04 every time I login I get a crash message:

FreemeteoWeatherScreenlet.py crashed with GError in load_buttons(): Icon 'gtk-close' not present in theme

If you have a similar crash message, you can simply install the gnome-icon-theme-full package which contains the gtk-close.png file.

Kernel mainline ppa downloader (aka kmpd / kmp-downloader)


About

kmp-downloader is a simple program that allows you to install fresh new kernel versions from the ubuntu kernel mainline ppa.

As it is, the mainline is not an actual "ppa" (personal package archive) and doesn't allow people to use apt-get to upgrade.

Requirements

You may need python beautifoul soup (python-bs4) or execute:
sudo apt-get install python-bs4

How to use it

You may download it using this quick link: https://github.com/medigeek/kmp-downloader/tarball/master

Save the archive and extract the files. Double click on kmpd.py (execute in terminal). If you're not sure about an option, press Enter and it will select the default answer.

You may also execute this command (one-liner):

cd /tmp; rm -rf medigeek-kmp*; wget --no-check-certificate https://github.com/medigeek/kmp-downloader/tarball/master -O kmpd.tar.gz; tar xzf kmpd.tar.gz; cd medigeek-*; python kmpd.py

You will be asked a series of questions, where you either reply by "Y" or "N" (yes or no) or simply press enter and let the program figure out the default reply (mentioned in square [] brackets). It will then install the appropriate debian packages.

Note: it will not fix the problems with other packages. I suggest running linux ppa packages without dkms package (without closed source packages like nvidia driver or virtualbox driver), in order to have a smooth, errorless installation.

Uninstall

To uninstall the kernel packages, remember to boot to a different kernel image first. Then you can use your favourite package manager to uninstall the packages.

If you prefer the command line, if you installed version 3.5.3, you can uninstall it using this command:

sudo apt-get purge linux-image-3.5.3.* linux-image-extra-3.5.3.* linux-headers-3.5.3.*

python: download url to file with progress bar

This is an alternative answer for a question on stackoverflow:
http://stackoverflow.com/a/22776/286994

I modified the answer a bit, using .format instead of % string formatting and sys.stdout.write(), and posted it on gist github: https://gist.github.com/3176958

#!/usr/bin/python
# Improve http://stackoverflow.com/a/22776/286994
# (using .format() instead of % string formatting)

import sys
import urllib2

file_name = url.split('/')[-1]
u = urllib2.urlopen(url)
f = open(file_name, 'wb')
meta = u.info()
file_size = int(meta.getheaders("Content-Length")[0])
print("Downloading: {0} Bytes: {1}".format(url, file_size))

file_size_dl = 0
block_sz = 8192
while True:
    buffer = u.read(block_sz)
    if not buffer:
        break

    file_size_dl += len(buffer)
    f.write(buffer)
    p = float(file_size_dl) / file_size
    status = r"{0}  [{1:.2%}]".format(file_size_dl, p)
    status = status + chr(8)*(len(status)+1)
    sys.stdout.write(status)

f.close()

I'm using this solution for the kernel mainline ppa downloader: https://github.com/medigeek/kmp-downloader

Now you can read xps files in ubuntu!

About
  OpenXPS or XPS stands for XML Paper Specification. It is based on XML and it's a new electronic paper format originally developed by Microsoft and it serves as a PDF alternative. XPS files are usually created using "Microsoft XPS Document Writer" in Windows environments. It is now standardized as an open standard document format.

Quoting Wikipedia:
 An XPS file is in fact a Unicoded ZIP archive using the Open Packaging Conventions, containing the files which make up the document. These include an XML markup file for each page, text, embedded fonts, raster images, 2D vector graphics, as well as the digital rights management information. The contents of an XPS file can be examined simply by opening it in an application which supports ZIP files.

 The OpenXPS document format specification supports features such as color gradients, transparencies, CMYK color spaces, printer calibration, multiple-ink systems and print schemas.

 Evince already supports xps, but it has to be compiled with that option enabled. In order for evince (the program that allows you to read pdf document files) to read xps files, libgxps is required first.

Status update
..for libgxps in Debian (we'll see about Ubuntu afterwards):



There's a PPA!
After much frustration, I have created a PPA for evince with xps: https://launchpad.net/~medigeek/+archive/evince-xps/

Note: The evince version in Ubuntu 11.10 oneiric ocelot doesn't work with xps (segmentation fault when opening the file) and there are several packages to be backported. I've decided not to backport it. It works in Ubuntu 12.04 precise pangolin.
If you need to read an xps file, package libgxps-utils provides enough conversion tools, e.g. command:
xpstopdf myfile.xps

How to set default apps (aka how to use xdg-mime)

How to set default apps in Chromium / Chrome / Firefox / Ubuntu Linux

Situation: You hate the default app that opens when you double click a file or when you open it with chromium browser and you want to change it.

a) In Unity (and probably Gnome 3 Shell), some default apps can be changed through gnome-control-center: System settings > System info > Default applications



b) You can also right-click on a file > select Properties > Open with. See what applications/programs are listed there. You can also add them and set them as default.


c) If none of the above work, you can use xdg-utils (xdg-mime) to set a default application for a specific Mime Type

First, you have to figure out what text string to use as a "mime type". An easy way to find it is to look into the default application's desktop file.

Example: Chromium opens magnet links and bittorrent files with transmission-gtk by default. The .desktop files are usually in folder /usr/share/applications/. We use "cat" command to look into the file /usr/share/applications/transmission-gtk (a line that starts with "MimeType"):

$ cat /usr/share/applications/transmission-gtk.desktop
[Desktop Entry]
Name=Transmission
[...]
Exec=transmission-gtk %U
Icon=transmission
Terminal=false
TryExec=transmission-gtk
Type=Application
MimeType=application/x-bittorrent;x-scheme-handler/magnet;
Categories=Network;FileTransfer;P2P;GTK;

Bingo! x-scheme-handler/magnet and application/x-bittorrent are the mime types we're after.

How to use xdg-mime command? Simple: xdg-mime default myapp.desktop mymimetype

..where we substitute myapp.desktop and mymimetype with the values from above.

Following the example above, we want magnet links and bittorrent files to open with Deluge (deluge-gtk) application. First you have to install the deluge-gtk package (otherwise the .desktop file won't exist). Then you have to execute:

xdg-mime default deluge.desktop x-scheme-handler/magnet
xdg-mime default deluge.desktop application/x-bittorrent
grep -i deluge ~/.local/share/applications/*

The last command (grep) should return "application/x-bittorrent=deluge.desktop" and the other mime type for magnet. Otherwise, something went wrong (maybe the desktop file didn't exist?).

And that's about it! Close and open chromium-browser again (or logout/login).

For the sake of documentation, the files that have to do with mime types and default apps are:

~/.local/share/applications/defaults.list
~/.local/share/applications/mimeapps.list
~/.local/share/applications/mimeinfo.cache
/usr/share/applications/mimeinfo.cache
/usr/share/applications/mimeapps.list
/usr/share/applications/defaults.list

Error creating XPS file


Error creating XPS file: Source _rels/.rels not found in archive
If you see the above error when trying to use xpstopng, xpstopdf, xpsto* tools provided by libgxps, then you probably suffer from this bug:
https://bugzilla.gnome.org/show_bug.cgi?id=670895

In short, the problem lies with libarchive versions prior to 3.x and zip files created by windows.
Solution?
a) Just update to 3.x or newer and you'll be good to go.
b) As a workaround, you can recreate the zip file:

unzip lorem-ipsum-and-image.xps -d temp/
cd temp/
zip ../newfile.xps *
cd ..


You now have a working copy of your XPS document.

How to install 1385:5f01 Netgear WPN111 (ar5523 driver)

Bus 002 Device 004: ID 1385:5f01 Netgear, Inc WPN111 (no firmware)
If you have the above device or a usb wifi dongle that requires ar5523 driver, you can try the commands and packages I've documented in order to make it work.

The weird thing with this device is that the firmware adds +1 to its ID. If you look at the code (SVN repository), you'll see that it's registered as "1385:5f00".

How to install the device driver
1. Install this package, depending on the version of ubuntu you may have:

2. Execute the following commands, copy-paste them one by one:
sudo apt-get update
sudo apt-get -f install
sudo apt-get upgrade
sudo apt-get install build-essential linux-headers-generic module-assistant
sudo m-a a-i ar5523-source
wget http://verein.lst.de/~hch/ar5523.tgz
tar xvf ar5523.tgz ar5523/uath-ar5523.bin --strip 1
sudo mv uath-ar5523.bin /lib/firmware

3. Restart your computer and replug your usb dongle. Hopefully it works. :)

How to enable man pages search in Google

 I was messing around with Google this morning, when I realised that you can actually "subscribe" yourself to a custom search for linux manpages. You have to be logged in of course. :-)

 I say "subscribed" in quotes, because it's not really a subscription, but rather a pointless (my opinion) feature. The only good thing about it is the icon that you notice directly what you want to search, giving a simple explanation of what the command does - in other words, the title of the manpage.

 The steps are quite easy! You go to http://www.google.com/search?q=man+nmap and press the "Sign in" link on the top right corner. You log in with your Google account, then you are redirected back to the Google search page.

  Afterwards, you go to Settings ⟶ Search settings.

 Next, scroll down to "Subscribed Links" and click on the Subscribe button next to the "Unix Manpages". Click "Save preferences" and you're redirected back to the "man nmap" search. The search result is listed third here, so the result might be different than yours.



 Finally, let me justify why I consider this pointless. If you use Firefox, you can easily integrate a quick search keyword with your favourite operating system's manpages website. Not all of them have this feature/website, but Debian and Ubuntu have it!
 - Head on to http://manpages.debian.net.
 - Select Man -> All sections -> Debian Sid.
 - Right-click in the white text box next to "Man Page or Keyword Search".
 - Select "Add a keyword for this search".
 - Name: Manpages, Keyword: man
 - Click Save.
 - Head to your location bar text box and type in "man nmap".

Voila! Have fun keyword-ing!

Blogger and Firefox - How to save your password

 Some websites don't allow you to save your password in Firefox built-in password manager, for example Yahoo and Blogger. Really irritating!

 One beautiful day (my irony tends to build up under 35 degrees Celsius), I noticed that the Blogger page actually redirects you to a Google account sign in. Therefore, I've come up with this little link that will allow you to save your password and take you back to Blogger:


https://www.google.com/accounts/ServiceLogin?service=blogger&continue=http://www.blogger.com/

Someone might make a good use of it. I also hope someone will find a way or fix the yahoo login page. Enjoy!

P.S. Make sure you install Secure Login add-on - it's a really handy application that allows one-click installs!

Workaround: brasero - slow speeds while burning

Brasero is a cd/dvd writing application for the Gnome desktop manager. Its advantages are ease of use, a lot of burning options and support for plugins!

Currently in Ubuntu 9.04, if you try to burn a disc, you might notice that:

  • Everything goes well until about 50%.
  • Afterwards, it continues, but the report does not show anything (empty progress bar).
  • The speed is less than 2x, from 600 KiB/s to 800KiB/s, but the burning keeps going.
  • Somewhere in the end, brasero shows progress again, but starts from 0%!!
  • Burn was successful.
Note: You should consider that this might not always be your issue with slow speeds. For example, maybe your drive is not working well, or maybe your power supply unit (PSU) does not have enough "W" to supply all your hardware with adequate power.

The bug information is extensively reported here:
http://bugzilla.gnome.org/show_bug.cgi?id=582261

One of the developers detected and corrected the problem, which seems that it was using the wrong plugin ("wodim" instead of "growisofs"). Since Ubuntu's binary package brasero has wodim as a dependency, it might cause problems if you try to remove wodim.

There is a workaround though that seems to do the trick:

Don't forget to install the package for growisofs: dvd+rw-tools

1. Tell brasero to use growisof:
  - Press Alt+F2, and execute this command:
gconf-editor 

  - Head to apps ⟶ brasero ⟶ config ⟶ priority.
  - Change the number "0" next to wodim-burn to "-1" in order to disable it.
  - Change the number "0" next to growisofs-burn to "1" in order to set a higher priority.



2. Instead of using "Max" in speed burning options, set it manually at a high speed - e.g. choose 16x for a DVD or 52x for a CD.

That's it!

belimantil.info hacked

About 2 days ago, I saw this on belimantil.info:




Astounded my first thought was "What the hell?!". I was looking for a revision text one of my colleagues wrote, and fortunately it was available on another site. medforum2 (a forum created by medical students for general talk, exams and medicine-related discussion) was hosted on that domain, I thought of visiting and saw one of my colleagues complaining about the same thing.

Today I re-visited the site, only to find that it wasn't working! Naturally, my techie side kicked in several minutes afterwards, and I started looking into whether it was their fault (probably) or the web administration (why not?). So the whois command revealed the nameserver, I decided to visit oklopsrbija.com, their hosting provider.

Poštovani klijenti,

Prekjuce je izvrsen napad velike grupe palestinskih hakera koji su "u borbi protiv Izraelaca" uspeli da zaobidju sve zastite na serveru i ishakuju sve naloge. Juce je ceo dan bila rekonstrukcija fajlova i pojacanje zastite.
Nocas je uglavnom proradilo sve. Otezan je jos pristup cPanelu. Klijenti kojima je hakovanjem ostecena indeks stranica a nemaju backup tog fajla, neka ostave ticket sa subjectiom: "backup index fajla" i uradice se parcijalni restore podataka za te klijente, pocevsi od petka ujutru, i samo za klijente koji zatraze restore indeks fajla. U nemogucnosti smo da uradimo full restore svih podataka posto je vecina sajtova, pogotovu foruma, vec online i pregazili bi tim full restore njihove sveze podatke.Probijanje zastite nije nista novo na internetu, postala je nazalost svakodnevnica, igrom slucaja smo prekjuce odabrani mi.
Ako hakeri mogu da provale u NASA ili Pentagon servere, sto ne bi i kod nas. I nismo prvi a na zalost ni poslednji domaci provajder koji je imao komplet ishakovan server.Takodje vas molimo da pratite dalja obavestenja logovanjem na vas oklopov nalog i pregledanje sekcije "Obavestenja".
S poštovanjem,
Vojin Petrović
direktor Oklop Srbija

In short, they are claiming that "Security breaking is nothing new on the internet, it has become an everyday event unfortunately, by chance we were chosen the day before yesterday" and "If hackers can break into NASA or Pentagon servers, why wouldn't they break into ours?". If understood them correctly, they're claiming it's not their fault they're not secure. Not even a single "We are sorry for not being careful" or "We'll take extra security steps to provide you with a safer hosting in the future" sentence. What an arrogance! I guess they should scratch the word on their website title, "Pouzdan" (=Reliable).

P.S. I hope this doesn't happen to me :)

How to change default locale (Ubuntu GNOME)

  I have always been a fan of English as my main language while using the computer or computer-related terminology. Recently I've stumbled upon the screenlets package (see picture or install debian package).
The only problem is that using United States' default date is shown as Month/Date/Year (i.e. 29/12/2008), which is rather unattractive (hey - my eyes, my brain, my opinion, my choice!).
  After many unsuccessful tries of various commands, I've come up with a rather graphical-based solution to use the locale I preferred. Obviously, the best choice for me would be en_GB (Great Britain/United Kingdom), since I wanted to stick with English, but use the date format Date/Month/Year.
  1. System > Admnistration > Language Support
Or you can simply run the command: gnome-language-selector
  2. Type in your password if asked to do so. (Make sure you're the adminsitrator, it might involve installing extra packages)
  3. Install your language of preference.
  4. Choose the language of your choice again as the "Default language".
  5. Press "Apply" and click "OK".
  6. Log out (System > Log out).
  7. While viewing the Login screen, click "Options" (lower left corner in Ubuntu), then "Set Language" and select "System Default". It will ask you to restart the login screen (press "Yes").
  8. When the login screen is restarted, you will be using the language of your preference with the appropriate locale! :) You should be able to check this out when you run the following command in Terminal (Applications > Accessories > Terminal):
locale

LANG=en_GB.UTF-8
LC_CTYPE="en_GB.UTF-8"
LC_NUMERIC="en_GB.UTF-8"
LC_TIME="en_GB.UTF-8"
LC_COLLATE="en_GB.UTF-8"
LC_MONETARY="en_GB.UTF-8"
LC_MESSAGES="en_GB.UTF-8"
LC_PAPER="en_GB.UTF-8"
LC_NAME="en_GB.UTF-8"
LC_ADDRESS="en_GB.UTF-8"
LC_TELEPHONE="en_GB.UTF-8"
LC_MEASUREMENT="en_GB.UTF-8"
LC_IDENTIFICATION="en_GB.UTF-8"
LC_ALL=


Now, if you notice any problems:
1. Execute these commands in terminal:
sudo -s

echo 'PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games"' > /etc/environment

2. Reboot your computer.
3. Run the gnome language selector again, choose "English (United States)" (or whatever was the default language). Press Apply and OK. Run it once more and set it again to the language you want it to be ("English (United Kingdom)"), press Apply and OK.
4. Follow the steps 6, 7 and 8 above.
You ought to be able to have the default language and locale you selected!

A second language - and a third one!

  One and a half year ago I wanted to comment an article about a second language. Sometimes people are having hard time learning new things, and it's not just their fault, it could be literally an anomaly in the brain structure or it could be related to the level of complication of the language someone chose to learn.
  To a personal background level, I believe I used to be a polyglot, a linguist if you will. I loved to learn new languages, I started English as a second language at the age of 9 (I think), all thanks to my wish to understand how to interact with the computer and read foreign literature. From there, I followed English until the GCE O'Level certificate. In the meantime, I began French for fun, having nothing to do during long summer days. The intensive 5-hour lessons proved to be a really attractive language and I continued learning for 3 consecutive years (during July/August). Then came preparation for the medical schools, which put a stop to all my other activities. Perhaps it was my teen-hormone years or my own free will that did not pursuit my love for new languages. Nevertheless, I've learned basic Latin and still continue to perfect my knowledge in Serbian language during my medical school years - I guess I still have a crave for languages deep down under the wish for wearing a white robe. :)
  No hard feelings to anyone, but I've recently compared the Serbian language to the German. Not that I know much about the German language, but I've noticed that in German there is the possibility to mix multiple words into one. Really cool once you get to know the basics of the language, but sometimes it is really hard for new learners. Basically, the grammar and the word pronounciation can be a reason for a person to pull back and not wanting to express themselves in that language. For example, Serbians from what I know have a hard time using "th" or "th"(d) - i.e. in the words "theatre" or "the" respectively - in English, which I think is one of the reasons they prefer not to use English at all.

  The fascinating thing as a child is that you can learn more stuff than an adult person, the so called "Tabula Rasa" thesis. My opinion is that gifted polyglots (people that speak a lot of languages) should nurture their languages by daily or weekly translating/reading text of headlines, otherwise the wealth of words and phrases of a language they might once perfectly knew will definitely decrease by time without giving it adequate practice. And it doesn't stop there, listening should adopt your hearing ability in order to rapidly process verbal requests or to better interact with other people. Remember, a dialogue needs "two to tango", so it might be better to find a partner for it. Exchanging opinions about your primary language for a secondary one through "The mixxer project" may prove really helpful. I haven't tried it yet, but some of the readers may have better solutions for this. I suppose that you'll have to make remarks about the difference in slang and normal language, so.. be very careful!
  Learning languages can be compared to other learning possibilities, such as playing the piano or the guitar or even writing code in various programming languages. There's a time when you might mix up words or phrases, but the brain learns to eventually adopt while multi-processing such requests - almost similar to other mechanical functions, like driving, eating a burger, talking to the phone and switching gears at the same time (not that I recommend it).
  To sum up, comparing time required, ability to learn and grace of use, as a child you'd have better results in learning a language, provided you often practice. And do practice, because in later years it will definitely prove worthy!

non-ASCII characters in usernames

Ever wanted a user name that is localised to the language you want, with your original name or surname and not only using Latin characters? Well, today I made a beautiful discovery!

Although a lot of people claim it is not possible yet for GNU/Linux to understand characters other than ASCII, I've found that it can concerning user names - using the useradd command (not adduser).

The actual problem seems to be a standard the unix commands have to follow:
http://www.opengroup.org/onlinepubs/009695399/basedefs/xbd_chap03.html

But it looks like the useradd accepts arbitrary usernames, which is cool! So I've tried my name in Greek:
sudo useradd -m Σάββας

Then adding a password:
sudo passwd Σάββας

And that is all that is required!! Maybe some programs aren't ready yet, but so far I've tried: terminal, console, firefox, rhythmbox, totem player. None of them returned any errors nor did they crash.

timekpr - Keep control of your computer usage

A rather new project, really reaaally really useful for parents and administrators that wish to limit their user accounts to a certain amount of login access duration or to limit accounts by defining access hours. Either way, it's a must have application, which I'm *ahem* actively co-developing! :)

The project page can be found at LaunchPad, the code is hosted at LaunchPad too! We have also set up a new blog for it at blogspot: http://timekpr.blogspot.com. There's a voting poll at the blog site, you might be interested to "give your click" to provide us with an orientation as to which new toys should timekpr focus on. ;)

I'm hosting a mini-page regarding the Debian packages, built with Ubuntu in mind: http://savvas.radevic.com/timekpr
(until I find some time to learn to cope with uploading packages to a personal package archive ["PPA"] at Launchpad)

Google - 403 Forbidden - "We're sorry"

If you got the "We're sorry" webpage I believe you came to the right place.. I have noticed this error myself :(

Error

We're sorry...

... but your query looks similar to automated requests from a computer virus or spyware application. To protect our users, we can't process your request right now.
We'll restore your access as quickly as possible, so try again soon. In the meantime, if you suspect that your computer or network has been infected, you might want to run a virus checker or spyware remover to make sure that your systems are free of viruses and other spurious software.
If you're continually receiving this error, you may be able to resolve the problem by deleting your Google cookie and revisiting Google. For browser-specific instructions, please consult your browser's online support center.
If your entire network is affected, more information is available in the Google Web Search Help Center.
We apologize for the inconvenience, and hope we'll see you again on Google.

At first I thought that they blacklisted Serbian IP addresses (that would be really spicy!). They may suggest some mumbo-jumbo procedure in Google FAQ, but that didn't do the trick.

The solution was rather easy, I went to http://www.google.com/sorry typed in some characters and voila - redirected to Google web search :)

Openoffice 3.0 final.. finally!

Today I noticed that the new version 3.0 of OpenOffice.org will be out, the open source/free desktop office bundle (that I adore). As osalt.com describes it:
 OpenOffice provides a great alternative to existing commercial office suites. It comes with word processor (Writer), spreadsheet (Calc), presentation (Impress), drawing and graphing tool (Draw), tool for creating equations and formulae (Math) and finally a database tool which also build reports and forms (Base). All components are multi-platform and multilingual. Development is sponsored by Sun Microsystems.
So I have two events to celebrate today, this and my birthday! :)

Click on the following links to see:
- the release announcement:
www.openoffice.org/news/index.html
http://www.google.com/search?q=cache%3Ahttp%3A//www.openoffice.org/news/index.html

- the new features:
http://www.openoffice.org/dev_docs/features/3.0/
http://www.google.com/search?q=cache%3Ahttp%3A//www.openoffice.org/dev_docs/features/3.0/

I've enclosed google cache links as an alternative, for some reason the openoffice.org site replies with '403 Forbidden' error.

Update:
You can obtain the openoffice suite from torrents or mirrors such as:
torrents: http://borft.student.utwente.nl/~adrian/bt.php
mirrorservice: http://www.mirrorservice.org/sites/down ... ble/3.0.0/

Firefox: "Secure connection Failed"

Visiting websites with secure connection enabled can sometimes lead to problems in Firefox. Websites just link their https certificate to whatever sub-domain they want or they redirect to another website without registering it properly. Mozilla Firefox 3 detects that "glitch" and adds an extra protection layer by stating the following error:
Page load error
Secure connection Failed

*site* uses an invalid security certificate
The certificate is only valid for *another site*
(Error code: ssl_error_bad_cert_domain)

There's an easy way to resolve this, if you click on "Or you can add an exception" → "Add exception" → "Get certificate" → Read the reason it was invalid and if you're OK with the reason → "Confirm security exception".
