cannot upgrade to ubuntu 20.04.1 LTS says
This was probably due to the fact that:
  * Unofficial software packages are not supported by Ubuntu
Please use the 'ppa-purge' command from the ppa-purge package
to uninstall software from Launchpad PPA

Probably a duplicate of: https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1889250

In other words, follow suggestion of removing nodejs and then trying the upgrade again: https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1889250/comments/2

[Brian Murray (brian-murray)]

Reviewing the files from your upgrade attempt you have installed nodejs from a location other than the offical Ubuntu archive. This version of nodejs is greater than the one in the official archive and is keeping some python packages installed which then prevents the upgrade from being calculated. Please remove nodejs along with any other packages from that archive and disable the archive. After that you can try upgrading again and if it still fails open a new bug report. Thanks and good luck!

Hi,
I removed node and nodejs and disable all items in "Software & Updates =>
Other Software"
and this helped to update for 20.04.1
Thanks.
