Sorry, I am slow to understand. My current Guix version is pre-0.15. So "guix pull" does not work anymore. This evaluation [1] contains a recent enough Guix to be able to pull, I guess. [1] http://ci.guix.gnu.org/build/1943556 I can download the derivation with: wget https://ci.guix.info/nar/gzip/bz1qqy225p1jlicwf07iiqr79icqddcv-guix-4de11dda7.drv But how to move the derivation to store? I am not sure that it makes sense. Well, the previous Guile snippet you have shown returns an error. My other approach is to clone and fetch a recent Guix from Git. Then: ./pre-env guix pull "bz1qqy225p1jlicwf07iiqr79icqddcv-guix-4de11dda7.drv" But I am not sure it will work because of the daemon.

Ahah! I am very slow to understand. :-) Cheers, simon
