guix pull symlink file exists

Occasionally I get an error like this. It happens for both the system
profile and my user profile, the "/root" part just changes to "/brad" when
it's to my user. My fix has been to delete the file and run pull again,
which works, but clearly isn't a permanent fix if the error comes back
later. I wonder if the migration message is a hint. Is it supposed to be
migrating stuff every time? I will hold off on deleting the file for now so
that I can try any suggestions for solving it properly. I just tried to do
the same as my user and didn't get the error, so maybe deleting it from one
affects the other. Not sure.

Migrating profile generations to '/var/guix/profiles/per-user/root'...
guix pull: error: symlink: File exists:
"/var/guix/profiles/per-user/root/current-guix"

my guix version: guix (GNU Guix) b634b5c253cb3351eb074c64be838f72aa83f54d

This sort of problem has occurred for others.  See, for example, this
post:

https://lists.gnu.org/archive/html/help-guix/2018-12/msg00107.html

Perhaps you accidentally ran a command as root which changed ownership
of a symlink from "brad" to "root".  It's possible to do that
accidentally because the "sudo" program is configured to behave
differently on different systems, so it may require slightly different
options than the examples you see from others or in the manual.

What are the outputs of these commands?

  sudo -E env | grep HOME

and

  sudo -HE env | grep HOME

Thank you,
