/admin/docker/repos 로드를 시도할 때 오류 코드: 500 오류 발생

[Milenski (JustMe)]

Discourse에서 무슨 일이 일어나고 있나요? 업데이트를 위해 관리자 페이지를 로드하려고 하면 다음 오류가 발생합니다: “while trying to load /admin/docker/repos Error code: 500 error”.

새 플러그인이 구현되어 시스템에 설치되었을 때 이 문제가 발생했던 기억이 납니다. 하지만 현재는 제가 직접 설치한 플러그인이 없으며, 내장된 플러그인만 사용하고 있습니다.

다음 명령을 실행했습니다:

cd /var/discourse
./launcher rebuild app

모든 과정이 순조롭게 진행되었지만, 관리자 패널의 업데이트 페이지에서 동일한 오류가 다시 발생합니다.

여기 /logs에서 가져온 백트레이스를 첨부합니다:

이 주제에 대해 알고 계신 분이 계시다면 도움을 주시면 감사하겠습니다.

[david (David Taylor)]

리포트 감사합니다. 수정안이 준비 중입니다:

FIX: Restore `Discourse::Version::PRE` (#37006)

latest에 반영되면 다시 이곳에 게시하겠습니다.

[bananaman]

오늘 업데이트를 설치한 후에도 같은 오류가 발생합니다. 재빌드(rebuild)를 해봤지만 도움이 되지 않았습니다.
어제는 업데이트가 정상적으로 설치되었고, 이전에는 이런 오류를 본 적이 없었습니다.

저도 같은 문제가 발생했습니다. 두 번 재빌드해도 문제가 해결되지 않아 수정을 기다리고 있습니다.

[david (David Taylor)]

지연된 점 죄송합니다 - 오늘 CI에서 몇 가지 무관한 문제가 발생했습니다.

수정사항이 이제 latest에 배포되었으므로, 다시 업데이트하면 문제가 해결되어야 합니다. 그래도 해결되지 않으면 알려주세요.

[Milenski (JustMe)]

확인합니다. 문제가 수정되었습니다. 터미널에서 다시 빌드한 후 모든 것이 정상입니다. 감사합니다.

[david (David Taylor)]

실패한 마이그레이션에 대한 논의를 별도의 주제로 분리했습니다:

'rename_discourse_rewind_disabled_to_enabled' 마이그레이션 오류

다시 빌드(rebuild)에 실패했습니다. 로그는 다음과 같습니다: discourse -c 'bundle exec rake db:migrate' rake aborted! StandardError: An error has occurred, this and all later migrations canceled: (StandardError) You must drop a column's default value before marking it as readonly I, [2026-01-08T16:18:49.016491 #1] INFO -- : Terminating async processes I, [2026-01-08T16:18:49.018961 #1] INFO -- : Sending INT to HOME=/var/lib/postgresql USER=postgres exec chpst -u postgres:postgres:ssl-cert -U postgres:postgres:ssl…

::PRE 오류가 해결되었음을 확인했으므로, 이 주제를 닫겠습니다. 보고해 주셔서 다시 한번 감사드립니다!
