cannot build system from source during the installation

[Adam Kandur]

hi guix!
I decided to try to build a guix system from source instead of using
substitutes but ran into a problem:

"guix pull --no-substitutes" returns me this

So I looked in the log and found that:

I checked http links. Can confirm that the source of linux libre is
not there. Maybe I did something wrong and you can help me to resolve
this issue.
