The Ubuntu 18 system is a brand new (to me) server. I had installed it as a testbed for U18 since I have not switched to it on any of my other servers yet. This is a completely new server (physically different than the U16 server I first used).
This is a Dell R720.

no VM, docker, this is normal install. I used the Roon install script.
No changes to the network stack. Hardly anything is on this system. I did a basic server install.
No other network-related programs beyond the default apache stuff.
This system doesnāt have a local library. I could sync my network drive (nearly 8TB) to a local
disk and point roon at that but then I couldāt reach the box remotely. Maybe I donāt fully understand the question about running with no network connection.
