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.
