mpd error - fatal_error: Failed to set group 45: Operation not permitt

For the life of me, I can't seem to get mpd+ncmpcpp to work. I've setup everything as per arch wiki now it won't load in systemd even when I run systemctl start mpd. service. I've rebooted god knows how many times nothing fixing anything. Please help. TQ

mpd error

~ ❯❯❯ mpd
fatal_error: Failed to set group 45: Operation not permitted

ncmpcpp error

Hello, can you paste here output from

mpd --no-daemon --stdout --verbose

Also, check /etc/passwd and /etc/group for mpd user/group and their ID. Default should be 45. From first error, it looks like there is some permissions problem.

Re: mpd error - fatal_error: Failed to set group 45: Operation not permitt

Hi, I managed to reproduce this problem when running MPD as non-root user.
When running as root, everyting works fine. You should read wiki article for per user MPD configuration. That will solve your problem.
