Roberto von Archimboldi<p>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.</p><p>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. </p><p>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.</p><p><a href="https://kolektiva.social/tags/HelpNeeded" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>HelpNeeded</span></a>, <a href="https://kolektiva.social/tags/PleaseHelp" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>PleaseHelp</span></a>, <a href="https://kolektiva.social/tags/Debian" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Debian</span></a>, <a href="https://kolektiva.social/tags/Hetzner" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Hetzner</span></a>, <a href="https://kolektiva.social/tags/Buster" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Buster</span></a>, <a href="https://kolektiva.social/tags/Bullseye" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Bullseye</span></a>, <a href="https://kolektiva.social/tags/HelpMyServerIsARadioactiveDisasterZone" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>HelpMyServerIsARadioactiveDisasterZone</span></a></p>
