Re: List available versions of package.

[Philippe Veber]

Hello everyone,

FWIW, I tried the exact example given in the manual [0] and it failed,
although for a different reason. It does a lot of work until it reaches an
exception (the build of profile.drv fails). Could someone confirm this
should work? Also, is it expected that packages from guix commits dating
from a few years ago will still work in this setting? Thanks!
