Hi, My disk was filling up, so I tried to run "guix gc", but I got an error instead: --8<---------------cut here---------------start------------->8--- $ guix gc -C 25GiB ... deleting `/gnu/store/n0gyzfw77ik35ld9d0d4737w88f11m4b-profile.drv' deleting `/gnu/store/fl7w0dlki7c906isiiflf9ka4c49zcmi-ca-certificate-bundle.drv' deleting `/gnu/store/ipn4xvvb3wrbx4lhzwdyyylvj42vyg6f-xdg-desktop-database.drv' guix gc: error: executing SQLite statement: database disk image is malformed --8<---------------cut here---------------end--------------->8--- What does this mean? How concerned should I be? How can I fix it? I looked for existing bug reports, but I didn't find anything. I haven't tried running the command a second time. FYI, I was building one package using my Guix installation via "guix build --cores=1", and another package using a Guix checkout via "./pre-inst-env guix build --cores", when I decided to run this "guix gc" command in another shell. I don't know if that matters. My expectation is that I can run GC even when building software, thanks to the guix-daemon's safe concurrent garbage collection algorithm. -- Chris
