[Bug 2084217] Re: I was trying to update my software from ubuntu 20.04 to 22.04.5 and faced this error: Could not calculate the upgrade An unresolvable problem occurred while calculating the upgrade. This was likely caused by: * Unofficial software packages not provided by Ubuntu Please use the tool 'ppa-purge' from the ppa-purge package to remove software from a Launchpad PPA and try the upgrade again. If none of this applies, then please report this bug using the command 'ubuntu-bug ubuntu-release-upgrader-core' in a terminal. If you want to investigate this yourself the log files in '/var/log/dist-upgrade' will contain details about the upgrade. Specifically, look at 'main.log' and 'apt.log'.

Reviewing the files from your upgrade attempt, you have installed nodejs
from the nodesource PPA. This version of nodejs is greater than the one
in the official archive and is keeping some 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!
