guix describe: error: failed to determine origin
hint: Perhaps this `guix' command was not obtained with `guix pull'? Its 
version string is ea54133367aad77a9e941fba18fe57ab3e1ab5d9.

I tried to update the guix daemon, but it failed with this error:
> sudo -i guix pull
-bash: warning: setlocale: LC_ALL: cannot change locale (en_US.UTF-8)

derivation from source

Is there a way to reinstall guix on a foreign distro? I couldn't find 
instructions on the manual, the only related thing it says is that I 
shouldn't unpack guix on an working Guix system[0].

Thanks for your help!
