OS 업그레이드. 14.04 -> 16.04. 재부팅 실패.

앞서 안쓰는 서비스들을 내리기는 했는데 지우려고 하니 실패하였다. kernel 이미지 버전들 때문에 문제가 되는거 같다. 아무튼 미루고 미루던 kernel 업그레이드를 다시 시도 해 보았다.

현재 버전은 3.19.0

junho85@junho85:/boot$ uname -r
3.19.0-39-lowlatency

예전에 메모 해 두기로는 아래처럼 적어 놨었는데 무슨 의미인지 기억이 잘 안남.

junho85@junho85:/boot$ sudo apt-get purge linux-image-3.13.0-70
E: dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to correct the problem.

암튼 이제 진행 되... 다가 실패. 근데 마지막에 70 이라 적혀 있는데 이걸 써라는 메모 였나?

sudo apt-get purge linux-image-3.13.0-70

sudo apt-get autoremove -f

뭔가 열심히 진행함. 용량도 조금씩 변화함. /boot 영역이 많이 필요하지는 않겠지만 너무 적게 잡혀 있는거 같음. 이거 사용중에는 바꿀 수는 없는건지 모르겠다.

다시 안쓰는 패키지 삭제 시도 하니 잘 삭제 된다.

New release '16.04.5 LTS' available.
Run 'do-release-upgrade' to upgrade to it.

모르겠다. gogogo

do-release-upgrade

그런데 이건 command line 용 방식이 아닌듯?

https://askubuntu.com/questions/5763/upgrading-from-the-command-line 에 보니 update-manager-core 를 설치 해 주라고 함.

sudo apt-get install update-manager-core

뭔가 한참 진행 하다가 404 Not Found 로 실패.

음. 재시작 해 보자.

sudo reboot

재시작 하다가 안되는 건 아니겠지.

재시작 하고 나서 접속이 안된다.

1:1 상담에 다시 글을 올렸다. 이거 부팅 할 때 직접 컨트롤 할 권한만 있으면 되는건데 1:1 상담에 의존하려니 좀 불편하다.
