Other relevant data:
I should note that I had previously manually created and added a new SSH key pair in EdDSA format (Ed25519).
It worked flawlessly before the dnf update.
Presumably, this problem will not affect other users widely, but only me, or very few users.
It seems that manual changes to Foreman config files shouldn’t be done directly on config files, as they will be overwritten by the next run of foreman-installer.
Is there a better, correct way of altering config files, where changes will remain preserved by foreman-installer?
Usually using foreman-installer parameters. In this case: --foreman-proxy-plugin-remote-execution-script-ssh-identity-file ? See foreman-installer --full-help.
Many thanks @JendaVodka , I agree your suggested solution is the best way to make this change.
However, the documentation isn’t quite clear how to specify the ssh key file. If the full path is used, the installed errors out. The configuration script really is a bit obscure, but it does work.
