The reason for this is relatively trivial: The library has moved on (currently version 0.0.5) through an OS Upgrade and hence cannot be found.</p>
<ul>
<li>Old version: <code>/usr/lib/aarch64-linux-gnu/libcamera.so.0.0.4</code></li>
<li>New version: <code>/usr/lib/aarch64-linux-gnu/libcamera.so.0.0.5</code></li>
</ul>
<p>Unfortunately you cannot simply link it to the old location. For crowsnest the solution is <link rel=dns-prefetch href=//github.com /> <a href="https://github.com/mainsail-crew/crowsnest/issues/143#issuecomment-1646048785#issuecomment-1646048785"
