I got the same error on Xubuntu from 7.04 to 7.10. The xubuntu-desktop was installed after an ordinary ubuntu instalation quite some time ago.
I have my logs attached to the bug report #154827 because this happened after that error installing cupsys, so I'm not going to attach them twice as they are exactly the same. -- package update-manager 1:0.81 failed to install/upgrade: ErrorMessage: SystemError in cache.commit(): E:Sub-process /tmp/tmppyNRYB/backports/usr/bin/dpkg returned an error code (1), E:Sub-process /tmp/tmppyNRYB/backports/usr/bin/dpkg returned an error code (1) https://bugs.launchpad.net/bugs/154253 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
