Assuming this information is correct, OP wants to check a file called similarly to jellyfin.list
in /etc/apt/sources.d/
and replace the word circe
with noble
(for the Ubuntu 24.04 codename) or trixie
(if noble gives the same error as circe). Keep in mind you need sudo/root privileges to modify this file.
Also
docker logs -f CONTAINERNAME
to see the log output for non-interactive containers.
