Hello,

Specifically, the message =E2=80=9CGuix is too old and cannot be upgraded=
=E2=80=9D
appears when you=E2=80=99re running =E2=80=98guix pull=E2=80=99 from Guix b=
efore 0.15.0,
released in July 2018.  (That seemed like prehistory to me but I realize
it=E2=80=99s only a bit more than one year old.)

But like Ricardo wrote, such problems are unlikely to show up again
because =E2=80=98guix pull=E2=80=99 since 0.15.0 is designed to handle all =
sorts of
bumps into future Guix revisions.

Anyway, the simplest option for now, melon, may be to remove your
current Guix installation and install 1.0 instead.
