Can't get my ssh to work after updating ubuntu
 

I upgraded by doing:
$ sudo apt-get update
$ sudo apt-get upgrade
$ sudo apt-get install update-manager-core
$ sudo do-release-upgrade

And now I can't get a ssh or scp connection! The damn provider support won't help me because they don't support any more recent version of ubuntu than 8.04. (which is too old for what I need )

So any Idea how I can get the ssh daemon running again ? I have access to a PLESK control panel -> I can modify files, start services and restart the server.

Thanks

Okay I managed to get an ssh connection !! started in "repair" mode. So now how can I find out why the ssh won't start in normal mode ?

Have you had a look in your log files? On my box, I'd check /var/log/messages, /var/log/syslog and /var/log/secure for information.
