<p>Today I tried upgrading from Kubuntu 22.04 to 23.10 using the
following command: </p>
<p>sudo do-release-upgrade<br>
</p>
<p>It went through the motions then came up with the following error
message:<br>
</p>
<blockquote>
<p>An unresolvable problem occurred while calculating the upgrade.
</p>
<p>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.</p>
<p><br>
</p>
<p>I read up on ppa-purge and gathered that it will uninstall a
program that was installed via a purged ppa if there isn't an
earlier version in one of the official Ubuntu repositories. <br>
</p>
<p>How am I supposed to know what ppa to purge? Am I supposed to
go through them one at a time until the upgrade is successful?
I imagine a horror story of purging a bunch of programs, not
remembering what they are then finding out over the next few
weeks as I try to run a program only to find it's not there and
figuring out how to reinstall it again.</p>
<p>Or is there something I'm missing?</p>
<p>thanks<br>
