![apt-get 업그레이드가 "다음 패키지가 예약되었습니다: python3-psycopg2"만 반환하는 반면 apt 업데이트에서는 업그레이드할 수 있다고 표시하는 이유는 무엇입니까(업그레이드 방법)?

저는 Debian10/KDE를 사용하고 있으며 몇 달 전의 패키지를 보관하고 있습니다. 그러나 sudo apt update대신 사용하면 sudo apt-get update추가 콘텐츠가 표시되고 "추가 버전"을 볼 수 있습니다.
왜 그런 겁니까? 이것도 apt-get에도 표시되어야 하지 않나요? 단순히 버전 2.8.5를 설치하면 안 되나요? (왜 안돼? 설치 방법?)

sudo apt-get upgrade해결책이 무엇이든, 새 버전을 설치하거나 설치하지 않으려면 실행할 때 최소한 프롬프트가 표시되어야 합니다 .

Postgresql 저장소의 stretch코드명을 다음으로 변경합니다 buster.
sudo sed -i 's/stretch/buster/' /etc/apt/sources.list.d/pgdg.list
그런 다음 다음을 실행하십시오.
sudo apt update
sudo apt upgrade
python3-psycopg2/stretch-pgdg 2.8.5-1~pgdg90+1 amd64 [업그레이드 가능: 2.7.7-1]
debian 저장소에서 제공하는 설치 버전을 postgresql 저장소에서 제공하는 버전 python3-psycopg2으로 업그레이드해야 합니다 . 하지만 업그레이드하기 전에 현재 설정된 2.8.5-1~pgdg90+1저장소 대신 debian Buster를 가리키는 올바른 저장소를 설정해야 합니다 .Stretch
