Whoops I Broke my OMV

Griffo · Dec 7th 2020

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 anyway. I wasn't really paying attention and blindly hit Y and proceeded to unistall most of OMV by mistake...

Whoops.

Thoughts on the best way to attack this? Fresh Install?

One can always hope this might work:

apt-get install --reinstall openmediavault

If not your OMV is so much toast.

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) running on the box

I've done:

apt remove openmediavault

apt autoremove

apt clean

Then followed the steps at https://openmediavault.readthe…stallation/on_debian.html

I get the console, but then when I try to log in I get the following:

Code

Error #0:

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

Then omv-engined would not auto-start so..

systemctl unmask openmediavault-engined

OMV-Extras would not re-install until I did a

apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 7AA630A1EDEE7D73

And apart from the fact that it seems to now cache my login in the browser (if i reboot it, it does not ask me to re-auth) it seems to all work fine.

FIngers crossed.
