Thank you for taking the time to report this bug and helping to make Ubuntu better. It seems that there was an error caused by a corrupted archive. Please execute the following commands, as it will clear your package cache, in a terminal ( Applications -> Accessories -> Terminal ) :
sudo apt-get clean sudo apt-get update Then try performing the update again. This will likely resolve your issue. If so please set the bug's status to Invalid. Thanks in advance! About your web browser problem: Try starting the browser from a terminal (see above) and see whether it gives any error message. Please file a new bug for this issue. ** Changed in: mono (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/668239 Title: package libmono-system2.0-cil 2.0.1-4ubuntu0.1 failed to install/upgrade: corrupted filesystem tarfile - corrupted package archive -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
