The bug message from the terminal looks similar to the #2 message from the bug 1163886, but I'm not sure if it is the same becasue I had no messages or reports about any signal 5.
I did not enable any PPA repositories including GNOME 3. They can be enabled only if they were enabled automaticly after installation of the system. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1255310 Title: after attempt to open ubuntu software center it shuts down in 3-4 seconds To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/software-center/+bug/1255310/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
