Hello Kai, Kai Mertens <k...@posteo.net> skribis:
> The command “sudo -i guix --version” gives me: > guix (GNU Guix) 20170703.13 This version predates the big ‘guix pull’ overhaul in 0.15.0 (what basically makes this kind of problem much less likely to happen.) Thus, you need a more recent ‘guix’ to upgrade. One way to do that is to fetch the derivation that builds a recent Guix and to build it. Here’s a trick to do that (for commit 57c7bfec6, on x86_64-linux): --8<---------------cut here---------------start------------->8--- $ guile -c '(use-modules (guix)) (with-store s (build-things s (list "/gnu/store/ihylk84symj8mjhp3zmy83ch2h2pl0ks-guix-57c7bfec6.drv")))' $ guix build "/gnu/store/ihylk84symj8mjhp3zmy83ch2h2pl0ks-guix-57c7bfec6.drv" $ /gnu/store/4zmf32hjrjjjl2xp91aldxhmsmk6ff29-guix-57c7bfec6/bin/guix pull --8<---------------cut here---------------end--------------->8--- Let me know how it goes! We should probably streamline that. Actually, it’s already almost automated: --8<---------------cut here---------------start------------->8--- $ wget -q -O - 'https://ci.guix.gnu.org/api/latestbuilds?nr=1&jobset=guix-modular-master' | jq '.[0]["derivation"]' "/gnu/store/ihylk84symj8mjhp3zmy83ch2h2pl0ks-guix-57c7bfec6.drv" --8<---------------cut here---------------end--------------->8--- The only thing that’s missing here is that currently “guix build /gnu/store/….drv” fails if the .drv doesn’t already exist, which is why the trick above resorts to a lower-level mechanism. Perhaps ‘guix pull’ should have a ‘--rescue’ option to do the trick above? HTH, Ludo’.
