팩맨 문제 - 지난 몇 달 동안 실패했습니다

Artix(Arch 기반) Linux를 업데이트하는 데 문제가 있습니다.

다음 명령을 사용하여 최신 미러 목록을 가져오고 팩맨을 시작합니다.

% sudo pacman -U ./artix-mirrorlist-20221209-1-any.pkg.tar.zst
% sudo mv /etc/pacman.d/mirrorlist.pacnew /etc/pacman.d/mirrorlist
% sudo pacman -Sy --needed archlinux-keyring
% sudo pacman -Syyu

과거에는 항상 성공했지만 지난 몇 달 동안 얻은 결과는 다음과 같습니다.

이러한 상황은 오랫동안 지속되었습니다.

그렇다면 이것은 내 요구 사항입니다.

나는 이 질문들에 대해 다른 답을 주려고 노력했지만 결과는 항상 같았습니다.

내가 뭘 잘못했나요?
