So the link indicates that the build has succeeded "19 hours ago", which would mean on May 9 around 14:30 UTC, which was about an hour before you wrote this message. > Are substitutes only available after the evaluation has completed? > --8<---------------cut here---------------start------------->8--- > $ guix describe > Generation 9 May 09 2023 15:18:11 (current) > guix c1ffe2f > repository URL: https://git.savannah.gnu.org/git/guix.git > branch: master > commit: c1ffe2f21bd1b9ba6bd527bbabe130144a69af71 > --8<---------------cut here---------------end--------------->8--- I think the substitute not being available may have to do with the difference between the package being available in the store, and as a nar file for substitution. As I understand it, the first request for a nar can fail, then it is built in the background, and a later request after a timeout will succeed. Hopefully offload specialists can correct potential misconceptions on my side ;-) Andreas
