Hello Konrad,

This was fixed in a subsequent commit:

  https://git.savannah.gnu.org/cgit/guix.git/commit/?id=8036b0942b89022147aaf9cd9940988fdbcc19ef

To work around it, you can pull from an older generation, along these
lines:

  ~/.config/guix/current-42-link/bin/guix pull

(This will work because this older guix won’t attempt to move your
generations to /var/guix/profiles, so it allows you to “jump over” the
bug.)

Let me know how it goes!

It’s terrible that a function like this that looks trivial has been
causing so much trouble.  Sorry about that.  :-/

Ludo’.
