Noblets12

Hello. After first install (Liya-7.2.1-x86_64.iso) I used sudo for move mirrorlist then run reflector. It's ok.
After i do
ame -Sy archlinux-keyring chaotic-keyring. I have the message
linux-api-headers : la signature de "Frederix Schawn freshwa@archlinux.org est de confiance inconnue
Le fichier /var/cache/pacman/pkg/linux-api-headers-6.7-1-any.pkg.tar.zst est corrompu (paquet non valide ou corrompu (signature PGP)).

@Noblets12 Firstly, sorry for the delay, I'm really sorry, the development of liya had stopped when i was undergoing depression, now i'm ok

Firstly, 7.2.1's support has ended, we are starting a new release series starting from 15th may, v1
(Rehana), we'd request you to use that iso image, do update me after that, btw, thanks
