The mechanism used by “guix pull” has changed.  These errors no longer
happen with the new mechanism.

~/.config/guix/latest is no longer used.  Instead “guix pull” installs a
full self-contained Guix to ~/.config/guix/current/bin/.

If you don’t have this you are likely upgrading from an old version of
Guix before that change was made.  In that case you need to upgrade to a
version of Guix that has a guile-gcrypt package, then install it, and
only then run “guix pull”.

With the new mechanism you can simply use any of the older variants of
Guix you have in ~/.config/guix/current-n-link/bin.

Hope this helps!
