[Bug 1982051] Re: Unable to install update-notifier-common

[Steve Langasek]

I'm afraid this error shows filesystem corruption, not a bug in Ubuntu.
You can check the kernel logs for more information.  A reboot with fsck
might help, or might render your system unbootable.  You should back up
any important data you have on the system before continuing.

  another:
  The package system is broken

  Check if you are using third party repositories. If so disable them, since they are a common source of problems.
  Furthermore run the following command in a Terminal: apt-get install -f
