[Bug 1876088] Re: Unable to upgrade to ubuntu 20.04

[Brian Murray]

You have python3.8 packages installed from the "deadsnakes" PPA which is
preventing the upgrade from being calculated. You'll want to remove
those packages and then the upgrade may be calculable.

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