The 20200524-ls67 tag fails to start the Jellyfin server with the following error:

According to the log Jellyfin looks for the directory with web files at /usr/lib/jellyfin/bin/jellyfin-web which does not exist.

seems a watchtower update broke this in my case. I fixed the version to

linuxserver/jellyfin:v10.5.5-ls54

which is working fine. On latest or nightly it fails.

@LaggAt ~what's a nigthly in this case? AFAIK CI is broken on Jellyfin and nightlies were not built for the last 3 months. So would that be constant updates of the Linux Server base or is Jellyfin built as well?~ <- EDIT: That's only applicable to jellyfin docker builds.

[KristupasSavickas]

Found the cause: jellyfin was split into jellyfin-servert and jellyfin-web in the latest master, changes not yet present in any release. The web files are installed to /usr/share/jellyfin/web on Ubuntu.

To fix this,/etc/services.d/jellyfin/run needs to be updated to run jellyfin with a --webdir=/usr/share/jellyfin/web command line argument. Not sure how to do this for nigthlies only as I'm not familiar with the Linux Server build process.

@KristupasSavickas great find and thanks for letting us know. We'll do a PR

Just so you know, different tags build from different github branches. This is the branch the nightlies build from: https://github.com/linuxserver/docker-jellyfin/tree/nightly
