Jesse Saenz<p>Setting up my first <a href="https://mstdn.social/tags/HomeLab" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>HomeLab</span></a> and installed <a href="https://mstdn.social/tags/ubuntuserver" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ubuntuserver</span></a> on an old MacBook Air…. I can’t even connect to my WiFi; I’m well out of my depth here 🤣</p>
mort<p>Okay this is wild: I just noticed that changing 'PasswordAuthentication' to 'no' in /etc/ssh/sshd_config is no longer enough to disable password authentication in <a href="https://fosstodon.org/tags/ubuntu" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ubuntu</span></a>. That's because Ubuntu Server now by default creates a sshd_config.d/50-cloud-init.conf file which contains 'PasswordAuthentication yes' which takes priority over sshd_config.</p><p>I would've unknowingly left password auth on if I hadn't double checked.</p><p>Why?</p><p>More: <a href="https://askubuntu.com/questions/1516262/why-is-50-cloud-init-conf-created" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">askubuntu.com/questions/151626</span><span class="invisible">2/why-is-50-cloud-init-conf-created</span></a></p><p><a href="https://fosstodon.org/tags/security" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>security</span></a> <a href="https://fosstodon.org/tags/linux" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>linux</span></a> <a href="https://fosstodon.org/tags/server" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>server</span></a> <a href="https://fosstodon.org/tags/ubuntuserver" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ubuntuserver</span></a></p>
Trixter of the Moon Council<p>Can anyone recommend a cheap, readily-available USB (or even PCI-E) WiFi adapter that'll get along with Ubuntu Server? I'm trying to set up an old desktop as a media server but the ancient dongle I have doesn't want to play along. I'm in the US, so stuff in Amazon is fine.</p><p><a href="https://retro.pizza/tags/Linux" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Linux</span></a> <a href="https://retro.pizza/tags/Ubuntu" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Ubuntu</span></a> <a href="https://retro.pizza/tags/UbuntuServer" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>UbuntuServer</span></a></p>

Gabriel Viso Carrera<p>It turns out Ubuntu Server performs an unattended upgrade right after install. Rebooting, powering off or kicking away your machine will cause a lot of broken dependencies.</p><p>How do I know? You guessed it!
