Samba server not installing

Tried to logon to samba tonight and would not connect. Restarted the system and no luck. Uninstalled and tried to reinstall - it would not install. Tried other addons and nothing will install…

No other issues that I’ve noticed have occurred.

Running 0.55.0 for a week with no problems. Where should I start looking/troubleshooting?

Running on Ubuntu 16.04 VM
