Music Player Daemon

Delete the files, and on the next update, MPD will remove the according entries from the database.

So what does that page say?
"When you do request help, post the following data"
Did you read that?

You didn't ask for help with your initial problem. You asked for help with a problem caused by you doing random things.

No, I'm not saying that. I wonder why you would think that - maybe because you havn't really read the page I linked to?

Your MPD version is very old and unsupported.
See https://www.musicpd.org/download-unoff-debian/ for how to get current MPD versions for Raspbian.

I meant that following the documentation (in the case of the satellite setup) leads to an error (in fact inability to use mpd player) So this is the real problem. And this is why you attempted to do random things contradicting with the documentation, which failed as well, of course. This path only ...

But the proceedings according documentation seems to does't work for 'windows satelites'...

I fail to grasp this sentence, this doesn't appear to make any sense. Rephrase.

You should follow the MPD documentation, and not make up something else and then wonder why it doesn't work.

so I think this is linux style. As I read in windows OS UNC Path is applicable.

What you think and read is wrong.

Something is wrong. Are you sure you want to use NFS? Because NFS addresses start with "nfs://" and have no backslashes.
See https://www.musicpd.org/doc/html/plugins.html#nfs

Strangely, the GCC website (https://gcc.gnu.org/onlinedocs/libstdc++/manual/status.html#status.iso.2017) documents that std::string_view is available since GCC 7.1, and you have GCC 9.3, so it *should* work. But it does not. Something is broken with your compiler installation, but I don't know what....

Your C++ compiler is too old. MPD 0.22 requires (as documented) a C++17 compliant compiler, but yours is not.

I have never run the script as root.

Don't use sudo!
Upload libmodplug's config.log.

This is a MPD 0.22 feature, but you're using 0.21.

Wait... I think I see the problem now.
"Pink Floyd - More.cue/track0010"

This is a virtual track inside a CUE file. And apparently, MPD cannot recognize that NFS error properly, and doesn't dig into just "Pink Floyd - More.cue" instead.

Can you write a bug report on GitHub about this?

But does the main MPD really use the same paths?
This error message originates from your NFS server, it's not just MPD's opinion that the file doesn't exist.... my educated guess is that there's an asymmetry in your path configurations.

Technically, you don't need a configuration file, so you don't need to create one.
Did you answer the questions I asked? If you need any further help, you should post the answers before asking more questions.

Does the file specified in the error message exist or not?
