Hello! I just encountered the following error while trying to build on master (commit 2bd84c50ff7a8dafe83b6aa89cd0f01d5282c621) with: --8<---------------cut here---------------start------------->8--- ./pre-inst-env guix build --system=aarch64-linux lib2geom The following derivation will be built: /gnu/store/vs11h35gq7fi90bm0h4ygi7ak4ihkck8-lib2geom-1.0-1.42e119d.drv building /gnu/store/vs11h35gq7fi90bm0h4ygi7ak4ihkck8-lib2geom-1.0-1.42e119d.drv... while setting up the build environment: executing `/gnu/store/x3gq648qnfnla7nppyfjvj62s2i8y7rl-guile-3.0.2/bin/guile': No such file or directory builder for `/gnu/store/vs11h35gq7fi90bm0h4ygi7ak4ihkck8-lib2geom-1.0-1.42e119d.drv' failed with exit code 1 build of /gnu/store/vs11h35gq7fi90bm0h4ygi7ak4ihkck8-lib2geom-1.0-1.42e119d.drv failed View build log at '/var/log/guix/drvs/vs/11h35gq7fi90bm0h4ygi7ak4ihkck8-lib2geom-1.0-1.42e119d.drv.bz2'. guix build: error: build of `/gnu/store/vs11h35gq7fi90bm0h4ygi7ak4ihkck8-lib2geom-1.0-1.42e119d.drv' failed --8<---------------cut here---------------end--------------->8--- The build log doesn't contain any more than the above no such file or directory error. Retrying the same commands leads to the same error message. The build machine is an offload Guix System machine running the qemu-binfmt service. The output directory, /gnu/store/3c0ihmfpazx3hkwyq3k0w8cdfi5ijdg4-lib2geom-1.0-1.42e119d doesn't exist yet, but I guess that's normal. A previous error (with the same message) when attempting to build plotutils led me to find out that the /gnu/store/2hibdxsj9f0zx3zilwh8phk1knk6y2fl-plotutils-2.6.tar.xz-builder file referred to in its /gnu/store/qcilzch61vsm9y4c3k4vbrl89g0fn8a3-plotutils-2.6.tar.xz.drv derivation did not exist, but retrying the build succeeded. Marius suggested restarting the guix-daemon, but it didn't resolve the issue after running it both locally and on the remote offload machine. A workaround was to 'guix copy /gnu/store/vs11h35gq7fi90bm0h4ygi7ak4ihkck8-lib2geom-1.0-1.42e119d.drv' then run 'guix build /gnu/store/vs11h35gq7fi90bm0h4ygi7ak4ihkck8-lib2geom-1.0-1.42e119d.drv' on that remote machine.
