[Bug 2084985] Re: Upgrading to LTS 24

Reviewing the files from your upgrade attempt, you have installed
packages from the deadsnakes PPA. Some of the packages installed are
newer than those in the official archive, which is keeping some python
packages installed which then prevents the upgrade from being
calculated. Please try using the ppa-purge tool to remove packages
installed from ppa:deadsnakes/ppa. After that you can try upgrading
again and if it still fails open a new bug report. Thanks and good luck!
