Regarding the error you've reported, it looks like you've a problem with your filesystem. Try cleaning the package cache and the perform the upgrade again.
If it happens frequently you should run the "Memory check" from the boot menu. If that runs successfully, please start the rescue system in the boot menu and select the "File system check" option in the next menu. Thanks in advance! ** Changed in: mono (Ubuntu) Status: New => Incomplete -- package mono-runtime 2.0.1-4ubuntu0.1 failed to install/upgrade: https://bugs.launchpad.net/bugs/533609 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
