It might be that you need to manually remove the ~/.config/guix/latest
symlink in root's home directory, and then run "guix pull" again.
Normally this is not needed, but in this case it might be needed to
recover from your current state.

As an aside: I'm not sure why you're running these commands as root.
Running "guix pull" as a user FOO effectively updates the package list
for user FOO, and not for any other user.  Running it as root is no
exception to this rule.  Each user, including root, has their own
private package list.

The main reason to run these commands as root is if you want to update
the packages in ~root/.guix-profile, or if you want to update a GuixSD
system.  Normally, each user runs these commands, including "guix pull"
under their own account.

As Leo said, unless you want to help us debug problems on core-updates,
it's best stick with 'master' for now.  'master' is the only branch that
receives timely security updates.  'core-updates' is a work-in-progress,
and at present there are many broken packages there.
