I encountered this error when trying to install additional multimedia packages. Then I noticed that I had Synaptic launched.
The cause of this error is that the apt package database is locked. After closing the application that holds the lock everything works fine. A user-friendly message is required. -- python2.6 crashed with SystemError in commit() https://bugs.launchpad.net/bugs/335897 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
