Issues running on dietpi distribution

[jkiddo]

Hi all - I'm experiencing some issues starting up the docker image when running it on the DietPi distribution (https://dietpi.com/): The output of starting the docker image is the following:

-and it just continues writing: [Error] (PosixStream) Connect exception: execve failed: No such file or directory. It never starts up

Well, this is not a problem with the distribution, but the armhf (aka. 32bit arm) image seems to ship a non-working librespot ;-/ Might be happening because I am building the armhf images on an arm64 machine. Will have a closer look..

[djmaze]

Okay, it is complicated. We cannot currently cross-build debian images because all official docker binaries for arm32 seem to be broken currently.

I just built the image manually on a real armhf device. Can you try if mazzolino/librespot-snapserver:arm works for you? I had to change the image so it also contains a newer snapcast version (0.22).

Seems to work ;)

FWIW, the console now logs the following:

I haven't mounted any config files into the container which is probably why the trace looks like the way it does. It would be a nice addition to the readme if it could be documented where the config files are placed inside the container. If I can find the time, I'll do a PR on that part
