minidlna fails to start on Raspberry Pi

[TheExpertNoob]

ERROR: Failed to open sqlite database! Exiting...
Exit code 255

Tested on a new image with latest 1.1.3 build on a different sdcard with none of my modifications as I thought some of my modifications/updates may have caused the issue initially.

Is it on the first boot or on a second boot where it did fail?
Did you apply the piratebox minidlna configuration like in this howto https://piratebox.cc/raspberry_pi:diy ?

[TheExpertNoob]

failed on first boot
applied piratebox config as stated from diy
rebooted, still failed.
uninstalled via pacman -Rs (removed dependencies)
removed minidlna.conf (and bkup) files
reinstalled with dependencies -S (asked which provider) (1) libx264 2) libx264-10bit) chose 1
stopped minidlna service manually
edited config manually to point to /mnt/usbshare/share/Shared as the media_dir
and db_dir=/opt/piratebox/share/minidlna
started minidlna service manually
started with no errors, so I enabled the service.
...waited for db to configure...
...rebooted...
no errors.
... and I believe I found the issue...
the example config points to /opt/piratebox/tmp which is owned by nobody:nogroup(755) and on the sdcard.
by manual editing the minidlna.conf file, I set it to /opt/piratebox/share/minidlna (for whatever reason, probabaly openwrt) which is on fat32 USB drive with full permissions (777/umask=0) owned by nobody:nogroup but all users including minidlna:minidlna can write to which minidlna runs as if not specified. so example script needs to be set as user=nobody OR the path to the db_dir needs to be changed for RPi.

I think the service under arch must be adjusted to run as nobody:nogroup , because this is the user context we are running in. This must be done during RPi image generation .. or we provide a copy of the minidlna.service in the src folder, which is copied over during activation.

BTW: good catch 👍
