Do you have any possibility to run guix pull with strace? strace is a 
program that logs all the system calls [1] of another program,
so you might see what operation is failing.

But for this, you must modify the startup file of guix-daemon! Because 
`guix pull` only forwards requests to `guix-daemon`, which
does all the work! I don't know how to do it in docker, but, for my Arch 
Linux system, there is a `guix-daemon` service file at
 /etc/systemd/system/guix-daemon.service.

There, you can find a line starting with "ExecStart=". This is the 
command to run the daemon. Prepend `strace -o 
/tmp/guix-daemon.strace.log` to the command to log all the system calls 
to the file /tmp/guix-daemon.stace.log

Hope that helps,
Moritz
