A little group I am part of has its own server. It hosts our website and a nextcloud instance. It is on a Hetzner machine. OK so far so good. The problem is that the person who set it up has left and I am the only one foolish enough to try to maintain it. The problem though is that I don't know how.
It is still running Debian Buster. I tried to follow a guide to at least upgrade it to bullseye, but something breaks. I think that it is something to do with its network configuration. This is mostly because I saw a comment that said if you are using a KVM Host with bridged networking, then you need to add bridge_hw eth0 (or whatever your network interface is called) to your network config otherwise the network won't start and you won't be able to reach the server. Weirdly I can SSH in after the upgrade, but the console shows lots of networky error messages and the website and nextcloud become unreachable.
Fine, I doubt any one will be able to help from that error description, but maybe you can point me at a foolproof guide to upgrading. I can't find one in the Hetzner docs.
