403 알래스카 앵커리지에서 금지된 업데이트 오류가 발생했습니다.

이상해 보이지만 앵커리지에서만 이런 일이 발생합니다. Ubuntu 18.04 LTS를 업데이트하고 "sudo apt update"를 실행하려고 하는데 다음과 같은 결과가 표시됩니다.

E: Failed to fetch http://security.ubuntu.com/ubuntu/dists/bionic-security/main/binary-amd64/Packages 403  Forbidden [IP: 91.189.91.38 80] 
E: Failed to fetch http://us.archive.ubuntu.com/ubuntu/dists/bionic-updates/main/binary-amd64/Packages 403  Forbidden [IP: 91.189.91.38 80] 
E: Failed to fetch http://us.archive.ubuntu.com/ubuntu/dists/bionic/universe/binary-i386/Packages 403  Forbidden [IP: 91.189.91.38 80] 
E: Some index files failed to download. They have been ignored, or old ones used instead.`

이것은 새로 설치한 것이며 앵커리지의 다른 가상 머신에서 동일한 오류로 여러 번 시도되었습니다.

나는 또한 캐나다의 다른 미러 사이트를 시도했지만 성공하지 못했습니다.

이해할 수 없는 일이지만 콜로라도에 있는 다른 사이트에서도 동일한 작업을 수행했는데 잘 진행되었습니다. 어떤 아이디어가 있나요?

이것은 내 /etc/apt/sources.list입니다.
