On e.g. debian this can be= enabled with 'sysctl kernel.unprivileged_userns_clone=3D1'. This message is apparently from bubblewrap, not from Guix. I suppose you might get this is you do =E2=80=98guix pack -R bubblewrap=E2= =80=99 and then try to run =E2=80=98bwrap=E2=80=99 from that pack: the =E2=80=98bwrap= =E2=80=99 executable already runs in a separate user namespace and might be unable to create one (?).
