Re: Guix home, guix system, channels, some noob questions

[Julien Lepiller]

Hi Sébastien,

When you run guix describe, it's running the guix for your user, which miggt be 
different from the one you run when you use sudo. That could explain why the 
modules are not found. I don't think guix home has anything to do with that.

I noticed that the first time you use sudo -E, whereas you use only sudo on 
step 5. Mayée that's why it fails?

I would run sudo guix describe and sudo -E guix describe to see how the two 
might be different from your user's guix :)

HTH!
