Thanks again doolio. But eeks, what have I done!
I saw running systemctl list-units:
guix-daemon.service loaded active running Build
daemon for GNU Guix
so the daemon is running, I can just start it manually whenever I want it.
I did do the Build-Environment-Setup.
I tried a command
guix package -i glibc-locales
bash: guix: command not found
as sudo also same result.
I found the steps to make the command available and tried
guix package -i hello as root and now it's going nuts, looks like it's
downloading the universe!
