While there were several headline-grabbing ransomware attacks during in 2017, another big threat started appearing at the same time that didn’t get the same coverage – illicit cryptomining.

I will have to look deeper into your last comment. Since I am unable to get to the path because of the permissions, I dont know the name of the log files that would be present there.

Martyn,
I prefer to diagnose the problem. Since the decision was made to run the Unifi Controller on Ubuntu, and i will be the one that has to support it, uninstalling and reinstalling does no good to me. I typed the above command. After that nothing is displayed.  Did i miss a step.

https://help.ubnt.com/hc/en-us/articles/220066768-UniFi-How-to-Install-Update-via-APT-on-Debian-or-Ubuntu  is what i followed.  Ironically, i install the Unifi Camera Server on Ubuntu 16.04 TLS with no issue.  I can, as you said try to uninstall or reinstall or even a new VM. We had already installed the Unifi Controller for switchers to a Server 2012 VM but decided to migrate it to Ubuntu. So, this is not mission or time critical.
Leigh KalbliAuthor Commented:
Yes it was installed.

Yes the VM is running on Dell R630 Power Eddge servers on vCenter 6.7  I looked in /etc and see no folder for unifi or no standalone file.
Leigh KalbliAuthor Commented:
Separate note, i am going to create a second VM as well.

After  running /usr/lib/unifi/bin/unifi.init start i get "starting ubiquiti contoller unifi cannot locate Java Home"  As you reference java being a problem, i thing this may be a critical piece linking the issue.  I will double check that java is correctly installed.  Thank you for your help

Be sure the correct JRE version is installed + setup in Unifi config files (per article).

I reached out to a friend who is more well versed than me and he was able to resolve the issue with Java that caused the problem.
