I am on Ubuntu 16.4 LTS.
I had ssh server running and it worked properly for many months, until one time when something cause it to fail.

Now, I can't do regular Ubuntu updates from Canonical. I can't run apt-get updates. E.g.

sudo apt-get upgrade python3

Reading package lists... Done

Building dependency tree       

Reading state information... Done

python3 is already the newest version (3.5.1-3).

Calculating upgrade... Done

The following packages were automatically installed and are no longer required:

  containerd libllvm5.0 libpaps0 paps python3-rlp runc swarm

Use 'sudo apt autoremove' to remove them.

0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

1 not fully installed or removed.

After this operation, 0 B of additional disk space will be used.

Thank you for help.

I don't know if this helps, but I have in /etc/init.d tow following 2 scripts...

ssh.sh

which appears to be the ubuntu provided shell script

and

ssh-start.sh

which contain

sudo service ssh start

in addition to all that, I also have /etc/systemd/system/sshd.service, which is a link to /lib/systemd/system/ssh.service

which contains:

[Unit]

Description=OpenBSD Secure Shell server

After=network.target auditd.service

ConditionPathExists=!/etc/ssh/sshd_not_to_be_run



[Service]

EnvironmentFile=-/etc/default/ssh

ExecStartPre=/usr/sbin/sshd -t

ExecStart=/usr/sbin/sshd -D $SSHD_OPTS

ExecReload=/usr/sbin/sshd -t

ExecReload=/bin/kill -HUP $MAINPID

KillMode=process

Restart=on-failure

RestartPreventExitStatus=255

Type=notify



[Install]

WantedBy=multi-user.target

Alias=sshd.service

I had the same problem, I used workaround 2 from this link SSH Server stops working after reboot, caused by missing /var/run/sshd

I think the issue for me is my kernal is too old, best of luck
