Oh, cool :)

That is the problem, "~/.cache/guile" is owned by root. I don't know
why, but I think it is not supposed to be root, so maybe we need to fix
it somewhere or mention it in trouble shooting. Anyway removing it
solved the problem and guix pull is able to continue.

Then I encountered another problem. In channels.scm, I was using (branch
"master"), and got this error:

--8<---------------cut here---------------start------------->8---
Updating channel 'guix-chromium' from Git repository at
'https://gitlab.com/mbakke/guix-chromium.git'...
guix pull: error: Git error: cannot locate remote-tracking branch 'master'
--8<---------------cut here---------------end--------------->8---

Changing it to '(branch "origin/master")' solved the problem. I mention
this because I have seen '(branch "master")' in a couple of places, thus
was wondering whether it is supposed to be the correct way.

Next, guix pull is finally able to compile chromium.scm, but
unfortunately failed to finish. This might not be a problem of guix
itself. However the error was "no code for module (gcrypt hash)", so I
think it is related. I have installed both libgcrypt and
guile-gcrypt. The following is the full error message:
