Hello Guix, I obtained a latest dev ISO for guix system and tried installing it just now. With the graphical installer, I received the error below for two times. Perhaps it's a bug?
In ice-9/boot-9.scm: 1685:16 1 (raise-exception _ #:continuable? _) 1685:16 0 (raise-exception _#:continuable? _) ice-9/boot-9.scm:1685:16: In procedure raise-exception: Throw to key `match-error' with args `("match" "no matching pattern" #<package polkit@0.120 gnu/packages/polkit.scm: 54 7f6e64aa7b00>)'. Command failed with exit code 1. Press Enter to continue. Thank you for all your work! Best Regards, Jin
