Description: Ubuntu 22.04.4 LTS
Release: 22.04

Running do-release-upgrade

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'.

Restoring original system state

I've tried all of the normal cleaning of source repos and disabling third-party repos. Nothing really helps. It looks like core pieces of Xubuntu are causing the problem from the logs and that shouldn't be the case.

Last few lines of /var/log/dist-upgrade/main.log are as follows:

Somehow lightdm-gtk-greeter is marked for uninstall.

MarkDelete lightdm-gtk-greeter:amd64 < 2.0.8-2ubuntu1 -> 2.0.9-0ubuntu3 @ii umU > FU=1

Is there a conflict between Ubuntu MATE and Xubuntu in how they configure lightdm perhaps?

Ever since running into this issue, do-release-upgrade acts as if there is nothing new available.

Checking for a new Ubuntu release
There is no development version of an LTS available.
To upgrade to the latest non-LTS development release
set Prompt=normal in /etc/update-manager/release-upgrades.

The ability to upgrade from on LTS version to the next is supposed to be a big advantage for Ubuntu. Until now, it's been reliable.

This seems related:
https://www.omgubuntu.co.uk/2024/09/canonical-halts-ubuntu-24-04-lts-upgrades-again

LTS-to-LTS upgrades to Noble seem to be having issues, and Canonical has disabled them for now.

Sean,

I would agree. Thank you for sharing this.

A few days ago, do-release-upgrade started reporting that a new version was available. I gave it a try but the outcome was no better. It seems to have a real problem with Xubuntu packages. It reports that I have held broken packages but "sudo apt-mark showheld" reports nothing nor does "sudo apt --fix-broken install"
