I enjoy working on selfhosted items and Jellyfin is in the mix. As with many software there are updates to them. Jellyfin seems to not have a great way to check for updates and install automatically. However, you can use the built-in API to help with that.
your method is great. another way to think about updating software like this would be in the docker container version. you can use watchtower to update them automatically. I personally use docker and this method for updates
I was just searching for a program like watchtower, I’m definitely going to check it out!
