Memcached 설치전 sudo apt update를 하면 에러가 납니다.
검색을 해보니 저장소를 바꿔야한다고 해서
kr.archive.ubuntu.com/ubuntu를 us.archive.ubuntu.com/ubuntu로 변경해도 안되고
sudo sed -i 's/kr.archive.ubuntu.com/mirror.kakao.com/g' /etc/apt/sources.list
이렇게 카카오로 바꿔 줘도 계속 같은 에러가 나면 어떤 이유일지 문의 드립니다.ㅠㅠ
감사합니다.

우분투 20.10 버전은 작년 7월에 지원 종료되었습니다. 지원이 중단된 버전은 업데이트를 위해 잠시 유지되다 미러서버에서 제거되므로 업데이트가 불가능한 것입니다.
LTS 버전(짝수년도 04버전으로 18.04, 20.04, 22.04가 지원중인 LTS 버전입니다)을 제외하면 우분투 지원기간은 9개월로 짧으니 버전 업데이트를 바로바로 하실게 아닌이상 LTS 버전을 사용하시는게 좋습니다.
