Thank you for taking the time to report this bug and help make Ubuntu better. However, the error message you describe has occurred because you interrupted some package installation / upgrade (because of power failure), and is not a bug.
To fix the problem, please follow the instructions in the error message (run "sudo dpkg --configure -a"). I'm closing this, as the instructions I have given you will fix the problem ** Changed in: synaptic (Ubuntu) Status: New => Invalid -- E: dpkg was interrupted, you must manually run 'dpkg --configure -a' to correct the problem. E: _cache->open() failed, please report. https://bugs.launchpad.net/bugs/288997 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
