Thanks for reminder about /var/guix/profiles. ❯ guix package -l | grep Generation Generation 158 Nov 02 2019 15:27:19 (current) ❯ ls -1 /var/guix/profiles/per-user/jone/ current-guix current-guix-16-link guix-profile guix-profile-158-link current-guix -> current-guix-16-link current-guix-16-link -> /gnu/store/bcbvw5n1pna08pj7zqfflb5zs9yfj90y-profile guix-profile -> guix-profile-158-link guix-profile-158-link -> /gnu/store/wb3b3mj3spny5jx2bj00imrwf5bjw373-profile ❯ ls /gnu/store/bcbvw5n1pna08pj7zqfflb5zs9yfj90y-profile/bin/ guix guix-daemon
But it didn't give me any useful information. Then I tried another command: guix gc --list-busy | grep icecat /gnu/store/ngsswh27mqxpynwrw6qyjsc3iql1ma3i-icecat-68.2.0-guix0-preview2 - Wow! Then reboot, and again 'guix gc' -> icecat-68.2.0 finally deleted! But that's only 50% of the solution: guix gc: error: cannot delete path `/gnu/store/50530hgnzkxgkqciip68dn7v23cslw1c-icecat-60.8.0-guix1' since it is still alive Any ideas?
