Additional fixes post installation
SSH connection refused
So today I tried ssh’ing into the desktop and no go. I was getting a connection refused and thought it had to do with either SSH not being installed or being blocked by the firewall. Later on when I checked, OpenSSH server was installed and the service was also running
sudo service status ssh
ssh start/running, process 2709
Hmm - this is weird. Next check was for iptables
and that was clear
too.. So last check was to look at /var/log/auth
and indeed, there’s a
problem. Interestingly machine keys weren’t generated during
installation

Aug 22 20:16:49 desktop sshd[1990]: error: Could not load host key: /etc/ssh/ssh_host_ecdsa_key
Ok - so the fix is easy - generate the keys with
sudo ssh-keygen -A
After that, everything’s back to normal :)
