I am upgrading through the software updater (update-manager) application after enabling "For any new version" in the software and updates application under the "Updates" tab for "Notify me of a new Ubuntu version" so that I may upgrade to 24.04. It should be noted that I just completed an upgrade from 20.04 to 22.04.
The upgrade stops and displays a splash that contains:
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'.
I used this (Could not calculate the upgrade, what happened?) page as a main source of help.
In the /var/log/dist-upgrade/main.log file I only found a single error towards the end:
2024-08-06 00:48:17,907 ERROR Dist-upgrade failed: 'E:Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.'
So I decided to check the /var/log/dist-upgrade/apt.log file by doing:
grep Broken /var/log/dist-upgrade/apt.log
Which gave me:

I have 35 broken packages according to pkgProblemResolver in this apt.log file. It is to be noted that this number was larger before. I got the number way down to 35 by removing wine and thunderbird (which I wasn't using anyways):
sudo apt-get remove wine && sudo apt-get remove thunderbird
sudo apt-get autoremove
sudo apt-get autoclean
sudo apt-get clean
Autoremove removed some unnecessary dependencies which brought the count down.
The splash calls attention to PPAs that are not provided by Ubuntu, but this doesn't seem to be the issue for me considering main.log does not give any error pertaining to a package or PPA, but to the pkgProblemResolver. Which prompted me to look inside apt.log.
After all this, I continue to receive the same splash mentioned before. I am very hesitant to remove any more packages from the list in apt.log, as I may remove an essential package for Ubuntu to upgrade or function.
Is the answer in apt.log or main.log?
How can I find out which packages of the 35 are the root of the issue?
I have searched through many online forums but none give a conclusive fix to the issue I have. I would be very grateful if anyone could supply any sort of information or help before I make a grave mistake trying to fix this myself.
