The problem is that there was a time window in March where
‘guile-bytestructures’ was broken as can be seen above.  This prevents
upgrade here.  :-/

The workaround would be to first upgrade to the commit before the one
you gave:

  guix pull \
    --url=https://git.savannah.gnu.org/cgit/guix.git/snapshot/6fe5c49ab487154074eaab2ef80e9a2f8163320c.tar.gz

and then upgrade again:

  guix pull

Jonathan, are you able to confirm that this works or did you work around
it differently already?

Thanks,
Ludo’.
