I have the Same Problem

Can you share the full log from the journal

journalctl -u radarr.service
journalctl -u sonarr.service
4

Here you have them in the files as they are big ones.

sonarrjournal.txt (451.2 KB)

radarrjournal.txt (621.3 KB)

Should be this: DietPi 10.4.2 update breaks Sonarr/Radarr/Lidarr · Issue #8158 · MichaIng/DietPi · GitHub

Fixed some hours ago in our updater. For those who updated earlier:

sed -i 's|/var/log/dietpi|/var/lib/dietpi|' /etc/systemd/system/dietpi-servarr_to_ram.service
systemctl daemon-reload
systemctl start dietpi-servarr_to_ram
systemctl start sonarr # radarr lidarr whichever you use

It worked thank you Need restart after the Commands

Right, either restart the respective services, or reboot the system.

It worked thanks for quick solution.
