Instead, the issue should come from this file:

https://bitbucket.org/x237net/alpine-guix/src/master/src/Dockerfile

I do not have carefully look to your files, but the issue should be:
 - wrong permission
 - /var/guix is not exposed

My intuition is that your issue comes from this other container.
And it builds, pulls etc because your are inside. However, if
something is wrong then the command "FROM x237net/alpine-guix" does
not do what you expect.

I mean, if the container x237net/alpine-guix is correct, you should be
able to just run this simple Dockerfile:

FROM x237net/alpine-guix:latest
RUN guix pull

(modulo set the correct paths and maybe start the daemon)

Last, aside the "Operation not permitted", check if the network is
correctly setup.


Hope that helps.

All the best,
