I think the evaluation [1] should do the job for i686.

The issue you encounter comes from a compatibility break in Guix. Four
years later (more or less I guess), inferiors has bee introduced in
Guix. They allow to go back and forward with "guix pull --commit=".
Well, other said, your version of Guix is too old to be updated using
the usual way.

The only way is to apply the Ludo's "trick".  If I understand well:
 1. Fetch a recent enough derivation of Guix
 2. Build this derivation with your old Guix
 3. Manually pull to populate the store
 4. Then the profile ~/.config/guix/ should be ok

If I understand well, your version of Guix is too old to use the
feature described in commit 9c9982dc0.

And if I still understand correctly, "pull --rescue" should be
mechanism to easily update an old Guix (before the overhaul in 0.15.0)
instead of doing all the dance.


All the best,
