Troubleshooting

Please note: upgrading from 8.10 (Hardy Heron) is NOT supported

If you get an error stating one of these possibilities:

  • Upgrading to a pre-release version of Ubuntu

  • Running the current pre-release version of Ubuntu

  • Unofficial software packages not provided by Ubuntu

try executing the following:

'sudo dpkg --configure -a' in a terminal.

Afterwards, reboot, and try the upgrade again. This should help to fix any broken packages that are missing due to upgrade problems.
