I’d perform sudo apt update and ensure all output lines are present (or explore your /etc/apt/sources.list and all ensure all repositories are present & enabled), then ensure you have applied all upgrades (ie. sudo apt full-upgrade and you’re not just using apt upgrade)
sudo apt update

Thanks for the instruction, but I seem to have another ongoing problem since yesterday or so, with upgrade of libfm-qt11, which I will mention in another thread.
Maybe that’s why I get the following ouput
apt install -s --install-recommends linux-generic
NOTE: This is only a simulation!
apt needs root privileges for real execution.
Keep also in mind that locking is deactivated,
so don't depend on the relevance to the real current situation!

You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
libfm-qt-dev : Depends: libfm-qt11 (= 1.1.0-3) but 1.1.0-2ubuntu1 is to be installed
linux-generic : Depends: linux-image-generic (= 5.19.0.19.19) but it is not going to be installed
Depends: linux-headers-generic (= 5.19.0.19.19) but it is not going to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).
but it is not going to be installed is because it is only a simulation, or it will not be installed because of some problem?
