[SOLVED] ncmpcpp: MPD: No Database

I've just decided to try mpd. When I installed and configure it in the first time, it worked out of the box. But after a reboot It's comes up with this mpd error. I checked my

~/.config/mpd/

folder there is a database file exist. I don't know where is MPD looking for database file. I checked

systemctl --user status mpd.service

MPD service is active and running. When I open up ncmpcpp it's saying Connected to localhost.. But no songs at all. When I'm pressing U there, it's saying

MPD: No database

How can I fix this?

Post your config, and the output of that status command.

Here is the mpd config at ~/.config/mpd/mpd.conf

And here is the output of

systemctl --user status mpd.service

Re: [SOLVED] ncmpcpp: MPD: No Database

The mpd.conf is missing some stuff,  i noticed it has no IP to bind too, and likely missing more see https://www.musicpd.org/doc/html/user.html

Re: [SOLVED] ncmpcpp: MPD: No Database

It doesn't need an IP to bind to it will just pick localhost:6600 by default. The status output is truncated however and I assume those first lines to be relevant, can you post that untruncated? Redirect into a file or use the --no-pager argument

To preempt a likely candidate, you did not accidentally enable the  system service of mpd? That will start beforehand, with a different configuration and block the user service. Make sure that the system service is disabled.

Re: [SOLVED] ncmpcpp: MPD: No Database

Thanks for correcting me v1del, I’ve used the same mpd.conf for years and guess I’m just accustomed to seeing those lines ; bind too address  & port. Regards.

Op
You could try

mpc update /path/to/mpdmusicdir

to update/create dB
The plugin warnings don’t matter however bind to already in use could be a factor, is MPD running elsewhere on your local network ?

I guess not. As I use ncmpcpp, I tried with

ncmpcpp update ~/Music

But it doesn't change anything.

Re: [SOLVED] ncmpcpp: MPD: No Database

Then see what’s using port 6600
Maybe you enabled service with sudo ?
hence MPD is already running similar to https://bbs.archlinux.org/viewtopic.php … 7#p1884997

Yep, the problem was same I guess.

I try to stop and disable the mpd service with

sudo systemctl stop mpd.service && sudo systemctl disable mpd.service

and get output with an warning.

 Warning: Stopping mpd.service, but it can still be activated by: mpd.socket

Then I try to locate system mpd.socket with

locate mpd.socket

and get

/home/kai/.cache/yay/mpd-git/src/mpd/systemd/system/mpd.socket
/usr/lib/systemd/system/mpd.socket
/usr/lib/systemd/user/mpd.socket

I remove the system's mpd.socket from /usr/lib/ and start the mpd service as user with

systemctl --user start mpd.service && systemctl --user enable mpd.service

It didn't fix the problem right away. I does require a reboot.
Thanks guys.

Re: [SOLVED] ncmpcpp: MPD: No Database

You shouldn't manually remove system files and the problem will likely return when the mpd package updates, just disable the socket as well:

systemctl disable mpd.socket

Thanks I'm learning about things.
