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 > Oh, I don't feel competent enough to give ideas, but “pull --rescue” > sounds too generic to me.

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, simon
