따라서 Ubuntu 18.04에서 20.04로 업그레이드한 후 시스템 설정이 사라졌습니다. gnome-control-center를 설치하여 문제를 해결하려고 하면 일부 충족되지 않은 종속성이 발생하여 수정을 시도했지만 작동하지 않았습니다. 필요한 설정을 직접 변경했지만 오늘 노트북을 다시 시작했을 때 오류 메시지가 표시되었습니다.

복구 모드에서 ubuntu-desktop 설치를 시도했지만(재설치하지 않고 놀랍게도 현재 설치되어 있지 않음) 작동하지 않고 다음 오류가 발생했습니다.

손상된 패키지가 있는지 확인했는데 dpkg --get-selections | grep hold결과가 없습니다.
, , 및 을 시도했지만
sudo dpkg --configure -a아무것도 변경되지 않았습니다.sudo aptitude install ubuntu desktopsudo apt-get -f installsudo apt-get update
집에 있었다면 Ubuntu를 다시 설치하겠지만 집에 없기 때문에 그렇게 할 수 있는 옵션이 없습니다.
의존성 문제를 해결할 수 있는 방법이 있나요? 재귀적으로 수동 설치를 시도합니다.의지하다: ...패키지는 이것이 유익한 노력이 아닌 것 같습니다.
편집: 실행하면 다음 grep -r deb /etc/apt/sources.list /etc/apt/sources.list.d이 제공됩니다.

답변1
좋아, 누구의 의견도 덕분에 해결책을 찾았습니다. 그래픽 드라이버의 ppa가 자동으로 업그레이드되지 않습니다. 달리기:
sudo add-apt-repository ppa:oibaf/graphics-drivers
sudo apt update
sudo apt upgrade
sudo apt-get install ubuntu-desktop
종속성이 해결되었으며 이제 시스템 설정도 다시 돌아왔습니다.
비슷한 문제가 있는 사람이 있는 경우: 의심스러운 항목이 있는지 출력을 확인하세요.
grep -r deb /etc/apt/sources.list /etc/apt/sources.list.d
내 경우에는 oibaf... 항목에 Ubuntu 18.04 버전인 "bionic"이 포함되어 있으므로 드라이버를 업데이트하면 올바른 저장소가 제공되고 모든 문제가 해결되었습니다.
