[Bug 1797606] Re: Ubuntu error on version update

[Brian Murray]

Thank you for taking the time to report this bug and helping to make
Ubuntu better. The error that you are a reporting is a conflict between
packages from the official Ubuntu archive and packages from a PPA. To
resolve this situation please deactivate PPAs using the tool 'ppa-purge'
which is provided by the ppa-purge package. Then try performing the
release upgrade again. Thanks in advance!

** Changed in: ubuntu-release-upgrader (Ubuntu)
       Status: Incomplete => Invalid
