Using Guix 3694c0d, the version is now 20.12.0 and https://bordeaux.guix.gnu.org provides all the substitutes. Note that “guix build --check” works fine too. BTW, this $ guix gc -D $(guix build -S) $ guix build -S --no-substitutes also works fine. In my case, downloading from . Indeed the sources of 20.8.0 does not seem available upstream. However, this version was not in Guix, AFAIK. For instance, git log --grep=kigo does not display a commit updating from 19.08.3 to 20.8.0. The only update is from 19.08.3 (d685f86054..f114a689e7) to 20.12.0 (908e48f7dd..3cd53b4500). The version 19.08.3 seems removed from upstream but we cannot do more; this source is still on ci.guix.gnu.org and should be transparently available via Disarchive. Well, I am in favor to close this bug. WDYT? All the best, simon
