@hgy59, I believe this should be the first of the *arr packages formally tested under DSM 7.2. Install and upgrade both succeeded with DSM 7.2-64216. It resolves the issue with the previous build which reported:

/var/log/packages/lidarr.log

2023/04/13 12:14:58	install lidarr 20221114-10 Begin start-stop-status start
/var/packages/lidarr/scripts/start-stop-status: line 151: 24133 Aborted                 (core dumped) ${service} >> ${OUT} 2>&1
2023/04/13 12:16:29	install lidarr 20221114-10 End start-stop-status start ret=[1]

Let me know if we are good to merge.

@publicarray, thanks for the approval.

EDIT: There was a new Lidarr released and I would prefer if that one be published (see #5698).
