Obtendo um erro ao executar o apt update: ModuleNotFoundError: Nenhum módulo chamado 'apt_pkg'

Quando corro apt updateem umUbuntu 18.04.6LTS, que é um servidor que minha empresa usa para hospedar o Netbox, recebo o seguinte problema:

Eu recebo um problema semelhante quando executo neofetch:

$ neofetch

    import apt_pkg

Um colega meu me disse para executá-los e tentar novamente, mas tive o mesmo problema:

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

Então fui verificar quantas versões do python estão instaladas neste servidor e conto 4:

Executá python3 --version-lo retornaPython 3.10.9

Alguém tem ideia de como posso resolver esse problema sem precisar migrar o aplicativo hospedado? Isso seria um pesadelo :(

EDITAR:

Mudei para /usr/lib/python3/dist-packagesprocurar apt_pkgvia ls -la | grep "apt_pkg.cpython"e encontrei o arquivo apt_pkg.cpython-36m-x86_64-linux-gnu.so, renomeei o arquivo para apt_pkg.soe agora posso executar apt updatecom uma nova mensagem de erro:

Responder1

por causa do arquivo /usr/lib/update-notifier/package-data-downloader, sua primeira linha contém isto:

#!/usr/bin/python3

a partir de informações futuras, seu python é Python 3.10.9,

e apt_pkg é apt_pkg.cpython-36m-x86_64-linux-gnu.so, o que significa que ele corresponde apenas ao python3.6, você pode fazer:

sudo rm /usr/bin/python3

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

certifique-se de que python3 --versionestápython3.6.x

execute o comando de atualização para um teste,

sudo apt update

Ubuntu 22.04.

Continuei recebendo avisos e avisos de erro quando tentei fazer isso apt update, os detalhes são como

Acontece que /usr/bin/python3estava vinculado a um endereço vazio. Quando verifiquei ls -ls /usr/bin/python*, há uma linha vermelha indicando que não está disponível.

O que achei útil foi redefinir este link com ln -s /usr/bin/pythonVERSIONAVAILABLE /usr/bin/python3.

Resolvido.
