problems scanning libraries after new install of LMS 8.3

After about 6 months of having removed LMS (7.9x) for various reasons, I have just installed the newest version on a fairly newly provisioned Ubuntu 20.04.3 server. [ I installed logitechmediaserver_8.3.0~1636104857_amd64.deb from nightlies ]

It generally seems to work fine with "SLIMUSER=squeezeboxserver"

System user "squeezeboxserver" was initially set to "nogroup" (I don't recall if this is the "normal" state of affairs for LMS installs) but I have assigned it to the group "users."

Regardless, this install of LMS can NEITHER scan the music library which is (recursively) owned by me:users with permissions set to 0754 NOR the playlist folder which is (recursively) owned by me:users with permissions set to 0774

Other users on the network can see the contents of the music library and can NOT write to the folders which is the desired behavior. Ideally LMS can not write to the libraries but CAN write to the playlists folder.

As a test:

• I chmod-ed a music subdirectory and all its files to 0774 and LMS can ALSO not scan that folder.
• I chmod-ed a music subdirectory and all its files to 0777 and LMS can ALSO not scan that folder.

Is it possible these problems are limited to the 8.3 nightly branch?


Any insights would be appreciated.

Also, to help me troubleshoot this, I don't seem to recall where I can find a document which clearly describes the permissions required by the LMS user (among other setup parameters)?

Thanks in advance!
