Thanks for testing this. Note that, if =E2=80=9Cwhich guix=E2=80=9D returns ~/.config/guix/current/b= in/guix, then none of the rollbacks above can have any effect. What could make a difference (but again, that would seem weird to me) is: guix pull --roll-back Are you passing extra options to guix-daemon, such as =E2=80=98--cache-failures=E2=80=99? Or did you enable offloading? It could also be that a transient failure is causing a silent build failure somewhere, as Jakub suggests. Thanks, Ludo=E2=80=99.
