Ubuntu 16.04 Python3 + dpkg + apt-get complètement cassé!
Peut-être que quelqu'un peut m'aider à traverser cet enfer:
Tout a commencé lorsque j'ai rencontré cette erreur: https://askubuntu.com/a/1034266/570817
et j'ai essayé de supprimer en quelque sorte l'installation de ppa:jonathonf/python-3.6 mais je me suis trompé en premier lieu et j'ai simplement supprimé les fichiers python3 dans /usr/bin/python3*
Ensuite, je suis allé plus loin avec la vitesse continue directement en enfer en essayant et en utilisant des indices différents sur des articles similaires, où, à partir de certains d'entre eux, je vais maintenant publier le résultat complet:
D'abord, je Sudo apt-get remove python3...
Ensuite, j'obtiens les sorties suivantes:
Sudo dpkg --configure -a

Comment puis-je réparer mon installation python3 défectueuse sur mon système, quand apt-get et dpkg en dépendent ??
Merci d'avance!
Nous recommandons généralement de ne pas modifier votre version installée de Python3 pour cette raison.
Lorsque les utilisateurs veulent utiliser plusieurs versions ou des versions plus récentes de Python , nous recommandons les méthodes d'isolation (telles que les ordinateurs virtuels, python (3) -virtualenv ou chroots) pour: éviter d'endommager votre système. Il n’existe pas de méthodes dans les dépôts Ubuntu - nous ne les fournissons pas.
Il est probablement possible de réparer votre système, mais cela n'en vaut peut-être pas la peine . Beaucoup de dépendances peuvent être manquantes. dpkg ne dépend PAS de Python3, mais apt le fait certainement. La stratégie de base consiste à utiliser dpkg pour réinstaller les paquets manquants dont vous avez besoin pour apt.
Visitez http://packages.ubuntu.com et téléchargez les packages python-minimal et python3-minimal et apt, puis installez-les à l'aide de dpkg. Cela peut prendre quelques itérations, car dpkg se plaint de dépendances manquantes que vous devez télécharger et installer dans le bon ordre.
En règle générale, la plupart des utilisateurs qui ont rompu ou manqué Python trouvent qu'il est plus rapide et plus simple de simplement sauvegarder leurs données et de procéder à une nouvelle installation.
