apt update 실행 시 오류 발생: ModuleNotFoundError: 'apt_pkg'라는 모듈이 없습니다.

내가 달릴 apt update때우분투 18.04.6 LTS(우리 회사에서 Netbox를 호스팅하기 위해 사용하는 서버) 다음과 같은 문제가 발생합니다.

다음을 실행할 때 비슷한 문제가 발생합니다 neofetch.

$ neofetch

내 동료가 이것을 실행하고 다시 시도하라고 말했지만 동일한 문제가 발생했습니다.

sudo apt-get remove command-not-found
sudo apt-get clean
sudo apt-get update
sudo apt-get install command-not-found

그런 다음 이 서버에 몇 개의 Python 버전이 설치되어 있는지 확인하러 갔더니 4개를 셉니다.

실행하면 python3 --version반환됩니다.Python 3.10.9

호스팅된 앱을 마이그레이션하지 않고도 이 문제를 어떻게 해결할 수 있는지 아는 사람이 있나요? 그건 악몽이겠죠 :(

답변1

file 때문에 /usr/lib/update-notifier/package-data-downloader첫 번째 줄에는 다음이 포함됩니다.

#!/usr/bin/python3

미리 정보를 보면, 당신의 파이썬은 Python 3.10.9,

apt_pkg는 apt_pkg.cpython-36m-x86_64-linux-gnu.sopython3.6에만 일치한다는 의미입니다. 다음을 수행해야 합니다.

sudo rm /usr/bin/python3

sudo ln -f /usr/bin/python3.6 /usr/bin/python3

python3 --version있는지 확인하세요python3.6.x

테스트를 위해 업데이트 명령을 실행하고,

sudo apt update

답변2

우분투 22.04.

시도할 때 계속 경고와 오류 메시지가 표시되었습니다 apt update. 세부 사항은 다음과 같습니다.

/usr/bin/python3해당 주소 는 무효 주소로 연결되어 있는 것으로 밝혀졌습니다 . 로 확인해 보니 ls -ls /usr/bin/python*사용할 수 없는 것을 나타내는 빨간색 선이 있습니다.

내가 유용하다고 생각한 것은 이 링크를 ln -s /usr/bin/pythonVERSIONAVAILABLE /usr/bin/python3.

해결되었습니다.
