Okay, FreeNAS 11 is still in Alpha testing. I just updated my VM of this machine about 20 minutes ago.
Guess I need to download Ubuntu 17.04 now, and what version are you running, Desktop, Server, Cloud, ..... But this will have to wait, the wife said she is ready to head into town. I'll come back to this later.
Also, have you tried an earlier version of Ubuntu yet?
