OK so I started again, and this time it seemed to go mostly fine. In case any other idiot does this, here's how I got it running
apt-get remove --autoremove openmediavault
Then instructions from https://openmediavault.readthe…stallation/on_debian.html
Thanks. I got various errors trying that, so at this point i'm just trying to get a completely clean OMV install. I'm OK with re-doing all the OMV config, but want to avoid re-doing the entire server as I have other stuff (HDHR, VIrtualBox, Unifi)…
Before I attempt anything, I thought i'd ask the guru's how you would approach fixing this.
I decided to try out AVAHI on the OMV server. It didn't work for whatever reason, so i immediately uninstalled it figuring i'd rather place it on another box…
