<sdb> I think I just found a bug in guix package -u. I am unable to run the updated package after running the upgrade. sdb1@antelope ~/guix$ echo $PATH /var/guix/profiles/per-user/sdb1/guix-profile/bin:/var/guix/profiles/per-user/sdb1/guix-profile/sbin:/var/guix/profiles/per-user/sdb1/guix-profile/bin:/run/setuid-programs:/home/sdb1/.config/guix/current/bin:/home/sdb1/.guix-profile/bin:/home/sdb1/.guix-profile/sbin:/run/current-system/profile/bin:/run/current-system/profile/sbin
