Well, a simple apt upgrade makes the openssh-server fail to install, and the only thing that can take away the package from that iF situation is a:
shutdown -r now apt install --fix-broken
Then a do-release-upgrade again broke the package with the same output plus:
User sessions running outdated binaries: ubuntu @ session #1: sshd[2389,2475,2887]
Again, reboot and fixbroken helped there.
Looking also on the side of snapd package, I found this bug 1958676 that might be related. So... what if systemd is the culprit???
