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 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1174253 Title: Segfault (core dumped) in gdk-pixbuf on upgrade To manage notifications about this bug go to: https://bugs.launchpad.net/gdk-pixbuf/+bug/1174253/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
