I am using Ubuntu 11.10. I was using GIMP 2.6 from the repo but I read that GIMP 2.7 has merged windows, I wish I hadn't but I wondered it and added the following PPA: matthaeus123/mrw-gimp-svn

After that it required me to add two other repos:

GIMP 2.7.5 Will not work with the current glib and gtk in Oneiric. To fix the problem install these repos

deb oneiric main

deb oneiric main

I added those PPAs and in somewhere a pop-up with "partial-update" appeared I applied the update and restarted Ubuntu. After the restart, my theme was a little bit changed, when I right-click the color is not gray but white and most importantly I am not able to reach:

  • Software Sources, when clicked it looks as if opening and then closes.

  • sudo gedit /etc/apt/sources.list doesn't work, because my Gedit doesn't work.

  • Preferences in Nautilus, when clicked it closes Nautilus.

I would like to revert everything I updated. I would like to downgrade/remove the packages ppa:gnome3-team/gnome3 and ppa:ricotz/testing PPAs but I am unable to do it.

So, I am stuck. How do I restore everything?

run "sudo apt-get -f install" might straighten out the partial update – Ringtail Mar 8 '12 at 21:27
Thanks for answer @BlueXrider, but nothing changed. Everything is same. – Şâkir Aşçı Mar 8 '12 at 21:36
Gimp 2.7.5 introduces new plugins which requires new libraries which in turn require a newer version of Gnome, that's why it's all messed up, for me and apparently for you Themes in newer versions of Gnome are broken. – Uri Herrera Mar 8 '12 at 22:25
Only way without re-installing is, get yourself another DE, completely remove everything Gnome, and re install the version in the repos. – Uri Herrera Mar 8 '12 at 22:26
Yes, that's exactly what happened, new libraries messed everything up. I was able to remove GIMP 2.7 and now GIMP 2.6 works; however, my Themes are broken, and most importantly Software Sources is unavailable both from Software Centre and from terminal. – Şâkir Aşçı Mar 8 '12 at 22:30
sudo apt-get install ppa-purge    

sudo add-apt-repository ppa:gnome3-team/gnome3    
sudo add-apt-repository ppa:ricotz/testing

*without previous two commands I had problems with "ppa-purge"

sudo apt-get update && sudo apt-get upgrade    
sudo ppa-purge ppa:ricotz/testing    
sudo ppa-purge ppa:gnome3-team/gnome3

Thanks for your answer, I found that solution somewhere and tried, but did not work. I mean, the packages were removed but my Theme and applications still don't work. So, still searching... – Şâkir Aşçı Mar 9 '12 at 12:45

I have found the solution!

As @solomenikmi said, I applied these commands:

sudo apt-get install ppa-purge    

sudo add-apt-repository ppa:gnome3-team/gnome3    
sudo add-apt-repository ppa:ricotz/testing

However, it did not solve the problem related to Themes and applications. So, I started searching and while searching I found a solution and applied the following:

sudo apt-get remove libgtk-3-common
sudo apt-get dist-upgrade
sudo apt-get install gnome-panel
sudo reboot

It seemed as if everything worked well; however, that solution was proposed for Ubuntu 11.04 but I am using Ubuntu 11.10 and it messed up the system again! This time, I was not even able to reach to login screen of Ubuntu, after I press the power button of my laptop, the start-up was freezing at Checking battery state... [ OK ]. After searching again, I applied those following commands:

sudo apt-get install lightdm-gtk-greeter
sudo apt-get install unity-greeter
sudo reboot

And that was it. I succeeded to return to the state where my themes and applications work just like before installing GIMP 2.7.5!
