SOLVED: Jellyfin update issue through Synology container

[Awacs]

Hello everybody !

I'm new to jellyfin.
I installed it on my Synology NAS after their decision to move away from the native video app.
I installed it on docker container and set it up without issue with config & cache folder on my NAS (cf screenshot)
When the first update was available, I stopped the container, updated through the Synology Container Manager app (cf screenshot) and then restarted Jellyfin.
Once I wanted to check a movie, the setup page appeared, asking me which language I wanted and then, asking me to create a profile.
When searching for the reason, I found that it could be due to config & cache folder not being on the NAS but it is not my case.

Do you know what is the issue I made ?

Can you show us how you mounted the config folder exactly?

I created a folder Jellyfin (which is misspelled) and then I copied the paths into the "Environment" part in the Container Manager

You need to provide a VOLUME for Jellyfin to write /config and /cache to. Setting the environment variables to write to a specific folder is not the same thing. That just means that Docker will write the temporary file system to that directory. Keyword TEMPORARY file system. When you upgrade it will wipe out that folder and start over.

Once you provide the volume, you will also need to reset those environment variables to ensure Docker will write data in the correct structure.

Code:

JELLYFIN_DATA_DIR=/config
JELLYFIN_CACHE_DIR=/cache
JELLYFIN_CONFIG_DIR=/config/config
JELLYFIN_LOG_DIR=/config/log
