Instead of hint, I propose this patch which displays:

--8<---------------cut here---------------start------------->8---
Updating channel 'guix' from Git repository at 'https://git.savannah.gnu.org/git/guix.git'...
guix pull: error: mkdir: Permission non accordée /home/sitour/.cache/guix/checkouts/pjmkglp4t7znuugeurpurzikxq3tnlaywmisyr27shj7apsnalwq
--8<---------------cut here---------------end--------------->8---

Somehow, the URL is already reported and the patch exposes the hidden
’directory’ variable whatever the error could be.
