I’ve used OpenMediaVault for years and liked it, but I’m just exploring some other options. I’ve got a new system with a Ryzen 370 and 890m iGPU, which Debian is fighting me on getting working. Meanwhile it looks like AMD is treating Ubuntu as a first class citizen for support. Just considering options, maybe Ubuntu plus Cockpit to abstract all the admin stuff?
This is a relatively new CPU. You might struggle on Ubuntu as well. As much as I love Debian, something like Fedora might be better.
It may be possible to get Debian running, though - either run Debian Testing or install a Backports kernel and Mesa. Were you failing to boot Debian, or did you just struggle after getting it installed?
Either way, I just don’t recommend Ubuntu.
