gnome-software trying to upgrade to Fedora 37

Description of problem:

Unable to upgrade from Fedora 35 to Fedora 36. The last regular updates did not help, now there's Fedora 37 but any attempt to upgrade fails. In the long term, this would prevent the system from receiving new updates and fixes rendering it unusable for no good reason as there shouldn't be any "special configuration", it's just a regular Fedora Desktop installation.

gnome-software just shows its usual oneliner and does not seem to log the error message anywhere (nothing in the terminal, /var/log/dnf.log doesn't seem to have the error either):
"Could not depsolve transaction; 1 problem detected:"
See attached screenshot.

Scripted attempts to upgrade using dnf fail with this confict:

Error: 
 Problem: cannot install the best update candidate for package mate-desktop-configs-1.26.0-4.fc35.noarch
  - problem with installed package mate-desktop-configs-1.26.0-4.fc35.noarch
  - package mate-desktop-configs-1.26.0-5.fc36.noarch conflicts with systemd-oomd-defaults provided by systemd-oomd-defaults-250.9-1.fc36.noarch
  - cannot install the best candidate for the job
  - mate-desktop-configs-1.26.0-4.fc35.noarch does not belong to a distupgrade repository



Version-Release number of selected component (if applicable):



How reproducible:

Always, impossible to upgrade anymore. It used to work until now.



Actual results:

The Mate Desktop environment seems to cause a conflict preventing the upgrade.
Plus, the official upgrade gui in Fedora fails to even show or log the error message again (see Bug 2042538).



Expected results:

Although it's common knowledge that third party installations and repositories can cause issues when upgrading Fedora, it shouldn't happen with a core component like Mate.
Comment 1 Wolfgang Ulbrich 2023-02-08 18:40:23 UTC 
Update must be installed with "dnf update mate-desktop* --best --allowerasing" which will be remove systemd-oomd-defaults.
