Bug Description
I was trying to upgrade from Ubuntu 18.04 to 20.04.1 . I installed the latest software updates as recommended. I started the upgrade process but keep getting this error
"Could not calculate the upgrade
This was likely caused by:
*Unoffocial software packages not provided by Ubuntu."
It recommended the usage of ppa-purge. I installed that command package.
Then I used the command " grep Broken /var/log/
I just started using Ubuntu so don't know anything about how all of this works. Can you help me out?
Thank you

Reviewing the files from your upgrade attempt you seem to have enabled a PPA that provides Xorg packages. This will prevent the upgrade as that PPA contains package version numbers greater than the release to which you are upgrading. You can revert the PPA by installing the ppa-purge package from the official Ubuntu archive and then running 'sudo ppa-purge ppa:kisak/ kisak-mesa' . After that you can try upgrading again and if it still fails open a new bug report. Thanks and good luck!
