Just a guess but I would try and link this and bug #804709 together. The problem I was having was installing the ATI driver from additional drivers, which would crash jockey and I think that it is also causing apt-daemon to crash as well.
How best can we confirm what the real cause of the error is? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/799982 Title: aptd crashed with SystemError: E:Sub-process /usr/bin/dpkg returned an error code (2) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/aptdaemon/+bug/799982/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
