Minidlna cant open log

here is what i get
/var/cache >>> sudo minidlnad
minidlna.c:781: fatal: Bad user ‘minidlna’.
also the file size is 0B

Make sure you have minidlna 1.3.1-1 from the Manjaro community repo installed, not some out of date, modified AUR package.

i have minidlna 1.3.1-1

The installed config sets the user to “minidlna”. But the user is not automatically created, if you want to use the user “minidlna”, you will need to create the user yourself. Or use a different user.

See the Arch wiki for more details.
