I think commit aa227b3be3d7728331a08dbd139c47c9b271dc23 fixes it. No matter how old the Guix you’re updating from is, you shouldn’t have this symlink problem. > There are probably a handful of our users who has old guix installations. > > This will not go away anytime soon unless we state very clearly how to > deal with it when they try to "pull".

No, I think that’s a misunderstanding of the problem. If you run ‘guix pull’ from 0.15.0, say, it will complete fine. Next time you run ‘guix pull’ or ‘guix pull -l’, it will automatically move ~/.config/guix/current-*-link to /var/guix/profiles/per-user/$USER. The bug was that this automatic migration was buggy prior to aa227b3be3d7728331a08dbd139c47c9b271dc23, which could leave you with broken symlinks. I hope this clarifies the situation! Thanks, Ludo’.
