Should I reinstall Ubuntu server or try to fix it?

[matelek]

I recently replaced my asus motherboard and the intel cpu in my server for an asrock b450m-hdv r4.0 and a ryzen 3 3200G.


After that I tried turning the server on, but it can't boot so I can't ssh into it, sometimes it just keeps spitting out "dbus.service". And doesn't start any services. Should I reinstall or try to fix it?


the exact error is

[FAILED] Failed to start Unbound DNS server
and when I go to check the status with systemctl this is what I get

❌unbound.service - Unbound DNS server

If you mean, you disconnected your root install media from the old motherboard, and reconnected it to an AMD motherboard/CPU, then expecting your root install to boot is a long-shot. I personally would not attempt to try to get that to work, others may have had success. I would suggest to make sure you first have a verified backup on other media somewhere, and then do a fresh install.
