Comment 32 for bug 1174253

I finally managed to solve the issue.

As everybody pointed out, I first needed to remove the webupd8team ppas.

After that, I had to downgrade the ligblib library and that's what was causing me a lot of trouble. The system didn't let me remove that library because of all the dependencies. I finally achieve that with the command:

sudo dpkg -P --force-all --force-remove-reinstreq libglib2.0-0

Once that done, still had to downgrade two related libraries glib-networking-common and gvfs-commonw with:

sudo apt-get install glib-networking-common=2.32.1-1ubuntu2
sudo apt-get install gvfs-common=1.12.1-0ubuntu1.2ppa8~precise3
