18.04.6 LTS를 다음 LTS로 업그레이드하고 싶지만 먼저 수행해야 할 업데이트가 있다고 생각하기 때문에 업그레이드할 수 없습니다. 그러나 이러한 업데이트는 작동하지 않고 "인터넷 연결 확인" 오류가 발생합니다. 이제 확장 지원으로만 제공되기 때문인 것 같습니다.
old-releases.ubuntu.com을 사용하기 위해 /etc/apt/sources.list를 변경해 보았지만 도움이 되지 않는 것 같습니다.

답변1
알았어, 내 /etc/apt/source.list를 old-releases.ubuntu.com으로 변경한 것이 잘못된 것 같은데 도움이 되지 않았지만 GUI에서 아래쪽 4~5개를 선택 취소하면 갑자기 업그레이드가 잠금 해제되었습니다. .
처음부터 모든 소스의 선택을 해제하는 것만으로도 효과가 있었을지 궁금하지만 아쉽게도 더 이상 이를 테스트할 수 없습니다.
업그레이드가 잘 된 것 같습니다.
