우분투(Ubuntu) 16 에서 18로 업그레이드가 안 될 때 해결 방법

어느 날인가부터 지속적으로 Ubuntu 18로 업데이트하라는 메시지가 떴는데, OK 알겠어 하고 버튼을 눌러도 반응이 없는 경우가 많았다. 여러번 반복되니 '이건 터미널에서 해결해야할 문제겠군'하며 터미널에서 이래저래 만져봤는데, 잘되지 않다가 결국은 업그레이드를 하게 되어 기쁜 마음으로 해결 방법을 공유한다.

본 경우는 Ubuntu 16.04 LTS에서 18.04 LTS로 업그레이드 한 후기이다. LTS는 Long-Term Support로 오랜기간 유지보수가 되는 안정화된 버전을 뜻한다.

문제는 크게 다음의 두가지 방식으로 나타날 것이다. 먼저 업그레이드를 하기 전에 다음의 명령어들을 입력해보자.

sudo apt update
sudo apt upgrade
sudo apt dist-upgrade
sudo do-release-upgrade

지금까지 본인이 설정해놨던 상황에 따라 각양각색의 상황들이 펼쳐질 것이다. 어쨌든, 계속해서 업그레이드에 실패했다면 다음의 두가지 경우였을 가능성이 높다.

Checking for a new Ubuntu release

1. No new release found.

2. Please install all available updates for your release before upgrading.

1번의 경우는 다음의 조치를 따라가보자.

터미널 창에서 다음을 입력하자

software-properties-gtk

Software & Updates

 

Download from의 서버가 잘 돌아가는지 잘 받아지는 것인지 확인하자. 필자의 경우 카카오 서버를 사용하다가 그냥 Main server로 변경했다.

Software & Updates의 Updates 탭

그리고 Updates탭에서 맨 하단의 Ubuntu version 선택을 그림과 같이 했는지 확인해보자.

2번의 경우에는 다음의 해결 내용이 도움이 될 것이라고 생각한다. 만약에 sudo do-release-upgrade를 입력했을 때 상황이 아래와 같은 방식이라면 잘 찾아오셨다.

중요한 것은 이렇게 무언가 upgrade가 되지 않는 패키지들이 남아있어서는 안되는 것이다. 이 때 해야할 일은 autoremove를 하라고 뜨는 경우 해당 명령어를 입력해준다.

sudo apt autoremove

확인을 묻는 경우 과감하게 y를 입력해주자. 다시 아래의 명령어를 실행해보자.

sudo do-release-upgrade

이번에도 안된다면, 아까 위 로그에서 짐작할 수 있는 부분이 있다. 'The following packages have been kept back', '1 not upgraded.' 이 부분이다. 필자의 경우에는 cuda-drivers라는 놈이 말썽이다. 아래와 같이 지워버리자.

sudo apt remove cuda-drivers

이번엔 아래의 명령어를 실행해보자.

sudo apt-get upgrade

위에서 설명한 것을 쭉 확인했고, 바로 위의 이 명령어를 입력했을 때 아래와 같이 출력이 된다면 아마도 업그레이드가 진행될 것이다.

의존성 때문에 다시 무언가 지우라고 나올 수도 있다. 이 경우는 이 부분을 적극 활용하자.

sudo apt autoremove

이제 다시 한번 아래와 같이 명령어를 입력했을 때 잘 동작한다면, 성공이다. 축하한다.
