I see.  I believe commit 099bb0175f681e5f68dafb8ad973866f31fe515c fixes
the problem.  With this commit, running ‘guix pull’ will always give
you, under ~/.config/guix/current, a new Guix running on Guile 2.2.

Could you try running ‘guix pull’ and see if it works now?

Besides, I’d like to drop Guile 2.0 support soon, so if you could tell
the COPR packagers to switch to Guile 2.2, that’d be great.  :-)

Thanks,
Ludo’.
