You can use the previous Guix to roll back. Instead of using =E2=80=9Cguix= =E2=80=9D just run /var/guix/profiles/per-user/$USERNAME/current-guix-110-link/bin/guix where the number corresponds to one before the current generation. That said: a segfault is highly unusual. Make sure that LD_LIBRARY_PATH is not set. (It forces potentially incompatible libraries to be loaded, which is a good way to trigger segfaults due to ABI differences.) --=20 Ricardo
