Unable to Upgrade 22.04 to 24.04 - An unresolvable problem occurred while calculating the upgrade

jstrines · May 1, 2025, 7:40pm

Hi Guys,

I am running - sudo do-release-upgrade

It then comes back with

Could not determine 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'.

When I look in the main.log I see the following error

2025-05-01 18:49:40,745 ERROR Dist-upgrade failed: 'E:Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.'

I then run update and upgrade and get

You should start with sudo apt full-upgrade before running the do-release-upgrade command… And make sure there are no held packages in the end…

Edit: also check that you do not have third party repos enabled that might potentially clash with package versions in the archive …

jstrines · May 1, 2025, 8:36pm

Hi Ogra,

Nothing needed done.

What does sudo apt install ubuntu-desktop^ do? (note the caret (^)). Does that want to install more stuff?

jstrines · May 1, 2025, 9:01pm

Yes it does, I installed it, is that OK?

ian-weisser · May 1, 2025, 10:55pm

Probably. It’s one step to returning your system to close to stock condition.
One assumes your data is properly backed up before starting a release-upgrade.
Now does your release-upgrade work?

jstrines · May 2, 2025, 3:33pm

Hi Ian,

No it doesn’t. Still the same errors

ian-weisser · May 2, 2025, 4:18pm

Okay, you tried the easy stuff.

Now it gets more complex and time-consuming. The problem is most commonly something you installed from among those many non-Ubuntu sources. Or perhaps something you removed.

The typical troubleshooting from here involves iteration: Review the apt log, uninstall non-Ubuntu software, disable a non-Ubuntu source, try the release-upgrade again. Rinse and repeat for each non-Ubuntu source. At some point you will uninstall whatever you originally installed that is causing the problem. Maybe you get it on the first try if you are handy at reading the log. Maybe not.

This is, of course, very much what your original output suggested:

jstrines:

* 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.

Decision Point: How much time and effort are you willing to invest before reinstalling becomes an attractive option?

That is one possibility among many.
Is this a kubuntu system?

Hi Guys,

Sorry for the long delay but yes i is a kubuntu system.
