Unable to reinstall nextcloud on TrueNAS because its running in shell

Hello all,

I have the following problem: I had uninstalled the Nextcloud plugin on my TrueNAS system and then wanted to reinstall it.

But now I can’t install it anymore because I get the following error message: Error: nextcloud had a failure Exception: JailRunning Message: nextcloud is already running! Partial plugin destroyed

Has anyone had this problem before? How did you solve it? Is it possible to stop nextcloud with a shell command? If so, which command?

I would be very grateful! Sorry, I’m very new to NAS and I’m not really fit with command lines.
