I'm getting this when running apt on Ubuntu 22.04 LTS:
$ sudo apt full-upgrade
Reading package lists... Done

The following packages have been kept back:
base-files gnome-remote-desktop gnome-software gnome-software-common

0 upgraded, 0 newly installed, 0 to remove and 19 not upgraded.
Now, these are only Ubuntu packages, so this is surprising. I've run the usual fixes such as sudo apt dist-upgrade and sudo apt -f install, but I keep getting the same output
