Thanks for taking the time to file a bug!

It appears that the post-install failed to start the SSH server. The latest version of SSH came only with 4 security fixes so it is not obvious what would be causing this:
http://changelogs.ubuntu.com/changelogs/pool/main/o/openssh/openssh_7.2p2-4ubuntu2.4/changelog

Can you verify your sshd config is valid by running `sudo /usr/sbin/sshd -t && echo PASS || echo FAIL` can you also try manually starting the ssh server via `sudo systemctl restart ssh.service` and see if any error message appear in `sudo systemctl status ssh.service`?

Hi, Solution from dna did not work for me.
I did the recoomended steps from robin this way:

1. sudo /usr/sbin/sshd -t && echo PASS || echo FAIL

Result: PASS

2. sudo systemctl restart ssh.service

Results:
Job for ssh.service failed because the control process exited with error code. See "systemctl status ssh.service" and "journalctl -xe" for details.

3. sudo systemctl status ssh.service

Any Idea?

From your log:

Feb 11 14:57:02 d........e sshd[12337]: error: Bind to port XXXXX on 0.0.0.0 failed: Address already in
Feb 11 14:57:02 d........e sshd[12337]: error: Bind to port XXXXX on :: failed: Address already in use.

The port you are trying to use already has something running on it.
