i am new to armbian not use to deb way.
that i use to rpm way from fedora. (it did work on pine64)
The problem is i need klipper to work for 3d printer, but did not work on fedora and i discovery most come from deb so i start doing on armbain because of pine64 arm.
i had problem apt update (first time tonight before no problem) give error and i had dig info but at end i wipe gpg off and apt key del all. and i found your link and rebutli. it seem work but gpg still do same error.
i would like clean gpg off and rebutli refresh and lastest gpg so i can get apt update to work. i did not know why it come out error like that tonight first time. it was work well than broken.
