Troubleshooting

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.
