I'd guess that Ubuntu, like Debian, by default disables the unprivileged
creation of containers.

What is the value of '/proc/sys/kernel/unprivileged_userns_clone'?

I think this is unrelated.

If you followed the instructions in the manual while installing Guix
[0], then your daemon's socket should be in /var/guix. When building
Guix from the Git checkout, did you set the value of localstatedir like
this when configuring?

$ ./configure --localstatedir=/var

If not, it defaults to '/usr/local'. If that's what happened, can you
reconfigure as shown above, and try Ludo's command again?
