Hello, Recently I've seen a couple of instances like these:
exporting path `/gnu/store/mi1rbw8fdsbi4bc4pndbb6smq39722vm-baobab-3.26.1.tar.xz' guix offload: error: build failed: hash of path `/gnu/store/mi1rbw8fdsbi4bc4pndbb6smq39722vm-baobab-3.26.1.tar.xz' has changed from `4223b4813b2253e68ea2b824d0d0e284ff75714ad0faf5a33d65a78df6b65915' to `77ac62e2629d8e45f624589c0c8bf99e24b3a722349bf1e79bc186008534e246'! cannot build derivation `/gnu/store/jbx6a4n1d55dpydr87d11m7xwapm3pcx-gnome-3.24.3.drv': 1 dependencies couldn't be built Without the build hook, it manifests as: starting phase `unpack' tar: This does not look like a tar archive xz: (stdin): File format not recognized tar: Child returned status 1 tar: Error is not recoverable: exiting now There was another instance on help-guix recently with a user having empty .drv files in the store. There is a bug lurking here somewhere, but I'm not sure where to start looking. $ find /gnu/store/ -maxdepth 1 -size 0 | grep -v '\.lock$' | wc -l 24
