Solved the ssh login taking 5 minutes, thanks to a power outage.


When logging back in - no motd.

When investigating that, found that update-motd wasn't completing.

When investigating why, found 
/etc/update-motd.d/99-livepatch-kernel-upgrade runs /snap/bin/canonical...

And, I had snapd.service masked.  Took 5 minutes to time-out.


systemctl umask snapd.service
systemctl enable --now snapd.service

with "UsePAM yes" in /etc/ssh/sshd_config

and login takes seconds again.


Weird, I don't remember masking snapd; it was probably quite a while ago.
