Jellyfin uses the same port as emby

[Paclanc]

I can't install Jellyfin since DSM says port 8096 is already used by other app. What can I do? I already tried changing emby's port, but app manager gives me the same error.

You may try and unzip the .spk file (just rename it to .zip) and edit the INFO file by changing the adminport="8096".

That did the trick, but I'm concerned future updates may be blocked for the very same reason.

If I remember correctly the DSM only checks during install and not upgrades. You can check this by installing the unmodified spk on top of the already installed version.
