Supprimé le binaire python et ne peut pas récupérer en utilisant apt-get, que puis-je faire?

11

Bien. Oui. Je voulais un nouveau départ parce que j'avais des confusions de dépendances, j'ai donc exécuté "whereis python" et effacé littéralement tous les fichiers et répertoires qui se sont présentés. Ensuite, lorsque je lance ppton apt-get install, j'obtiens bien sûr beaucoup d'erreurs. Existe-t-il un moyen de réinstaller python sur Ubuntu sans simplement effacer?

Voici le résultat de la tentative d'installation du binaire python:

root@ubuntu14-server:/home/kpoole# apt-get install python

À l'avenir, ne faites pas ça. Ne supprimez pas manuellement (ou ne salissez pas) les fichiers installés via les outils de gestion de packages (sauf s'ils sont explicitement configurés pour cela, comme les fichiers de configuration, etc.).

Cela étant dit, si vous ne parvenez pas (et il semble que ce soit le cas) à utiliser apt-getpour récupérer de cette situation car certaines parties du processus s'attendent à ce que python soit déjà installé, vous avez quelques options (pas toutes fonctionnera nécessairement).

Vous pouvez récupérer les .debfichiers python (et les fichiers associés) manuellement et tenter de les utiliser dpkgpour les installer manuellement (vous devrez résoudre manuellement l'ordre de dépendance pour vous assurer que cela fonctionne correctement). Quelque chose comme:

apt-get download python2.7-minimal ## at least this package is necessary
sudo touch /usr/bin/python2.7 && sudo chmod +x /usr/bin/python2.7
sudo dpkg --unpack python2.7-minimal*

Vous devez vérifier les autres fichiers binaires manquants, comme pycompile, et appliquer la même solution.

Après cela, il est recommandé de vérifier la base de données dpkg à la recherche de packages non configurés, semi-configurés et simplement décompressés:

sudo dpkg --check

Lisez les messages et appliquez les correctifs, mais normalement cela demanderait sudo dpkg --configure -a. Un sudo apt-get -f installpourrait aider en fonction de la situation.

Vous pouvez également utiliser un mode de récupération (ou réinstallation) du support d'installation pour résoudre ce problème.

Existe-t-il un moyen de réinstaller python sur Ubuntu sans simplement effacer?

Oui. Réinstallez sans formatage.

Ce sera également la méthode la plus rapide pour résoudre ce problème, car vous avez probablement déjà un DVD Live.

— Rinzwind

La réinstallation d'ubuntu semble un peu exagérée dans ce cas.

— ike

Puisque presque tout dépend de python et que "apt" ne fonctionnera plus (en raison des dépendances de python), toute autre méthode prendra beaucoup plus de temps. Une réinstallation sans format prend environ 10, 15 minutes sur une machine actuelle. @ike

apt devrait fonctionner pour d'autres packages, mais pas pour python. Il n'est pas trop difficile de résoudre ce problème en réinstallant chaque package.

La suppression d'un système binaire peut être cataclysmique, mais ce n'est pas la fin du monde. Vous pouvez le supprimer rmet le récupérer facilement . Python n'est qu'une promenade dans le parc.

Ouvrez un terminal et saisissez les commandes suivantes:

Premier essai

sudo apt-get -f install

Si cela ne fonctionne pas, essayez

sudo dpkg --configure -a

Si vous rencontrez toujours des problèmes, exécutez

sudo apt-get install --reinstall python python-chardet python-colorama python-distlib python-django python-django-tables2 python-six python-html5lib python-lxml python-minimal python-pkg-resources python-setuptools python-urllib3 python-requests python-pip python-virtualenv

En dernier recours, vous devrez peut-être supprimer ces packages avec la commande suivante, puis réinstaller ces packages à l'aide de la commande ci-dessus. Si tel est le cas, vous devrez faire très attention. Il y aura une liste de packages désinstallés avec la commande suivante. Vous devrez copier cette liste et la coller dans gedit. Avec gedit ouvert et la liste des packages collés dans gedit, appuyez sur ctrl+ het entrez \ n suivi de deux espaces dans "Rechercher" et d'un espace dans "Remplacer par" pour supprimer tous les paragraphes et espaces supplémentaires avant de cliquer sur remplacer tout pour que votre liste contient une liste de packages séparés uniquement par des espaces simples.

sudo apt-get purge python-chardet python-colorama python-distlib python-django python-django-tables2 python-six python-html5lib python-lxml python-minimal python-pkg-resources python-setuptools python-urllib3 python-requests python-pip python-virtualenv

Enfin, exécutez: sudo apt-get installet collez la liste des packages de gedit pour tout réinstaller.

Je suis presque certain que tous les packages python- * sont inclus dans le méta-package python. OP n'aurait pas besoin d'établir et de maintenir une liste de packages à (dés) / installer. apt-get install --reinstall pythondevrait le couvrir.

— amanthethy

@amanthethy la "liste" que je mentionne est les centaines d'autres packages qui peuvent également être désinstallés tels que l'unité, toutes les étendues, le gestionnaire de comptes, etc. .

Non, cela ne fera de mal à personne - à part l'étrange tunnel carpel - mais ce n'est pas nécessaire. En outre, python-pip est un gestionnaire de packages pour les programmes python. C'est une application construite en python et non une fonctionnalité du langage lui-même.

sudo apt-get install --reinstall ubuntu-desktopcouvrira tous les extras que vous avez mentionnés. [unité, étendues, python, gestionnaire de comptes, etc.]

Pas de soucis mec. Les votes négatifs ne signifient pas grand-chose pour moi tant que nous sommes en mesure d'aider le PO :)

Vous devez supprimer chaque package qui vous pose problème, puis les réinstaller.

Voir /ubuntu//a/32899/176376 pour la suppression sans supprimer les dépendances.

sudo dpkg -r --force-depends "package"

sudo apt-get install "package"

Vous devez d'abord supprimer tous les problèmes, puis les réinstaller.

Exécutez un sudo apt-get install -fet sudo dpkg --configure -atous les quelques commandes.

Je vois que vous avez des erreurs comme celle-ci:

python2.7: not found

Cela signifie que l'exécutable python 2.7 est introuvable. J'ai utilisé ces commandes pour trouver le paquet qui le contient (cela ne fonctionnerait probablement pas sur votre système cassé, cependant)

$ which python2.7
/usr/bin/python2.7
$ dpkg -S /usr/bin/python2.7
python2.7-minimal: /usr/bin/python2.7

Vous devez le réinstaller, mais vous devez d'abord parcourir ses dépendances. Utilisez ces commandes pour les répertorier:

$ apt-cache depends python2.7-minimal
python2.7-minimal
  Depends: libpython2.7-minimal
  Depends: zlib1g
  PreDepends: libc6
  Suggests: binfmt-support
    binfmt-support:i386
  Recommends: python2.7
  Conflicts: binfmt-support
  Conflicts: binfmt-support:i386
  Replaces: python2.7
  Replaces: python2.7:i386
  Conflicts: python2.7-minimal:i386

libpython2.7-minimal est probablement endommagé. Je vous recommande donc de commencer par émettre:

sudo apt-get install --reinstall libpython2.7-minimal

puis:

sudo apt-get install --reinstall python2.7-minimal

puis j'espère que votre

sudo apt-get -f install

allons réussir.

C'est un comportement attendu. La suppression de fichiers n'est pas la même chose que la désinstallation d'un package ou d'un programme.

Vous avez supprimé tous les éléments liés à python de votre installation, mais votre gestionnaire de packages ne le sait pas. Lorsque vous allez réinstaller Python, apt s'attend à ce que tous ces fichiers soient toujours là et ne prend pas la peine d'essayer de les télécharger à nouveau. En ce qui concerne apt, tout python est toujours installé; Vous ne l'avez jamais dit autrement.

Vous pouvez essayer ce qui suit pour tenter de corriger cela:
sudo apt-get install --reinstall python

À l'avenir, désinstallez les packages en utilisant apt-get removeou apt-get purgeou graphiquement à partir du Centre logiciel Ubuntu.

Une purge de python désinstalle de nombreuses dépendances, où la réinstallation ne réinstalle pas toutes celles-ci.

Vous avez raison jusqu'au deuxième paragraphe. Votre méthode de «correction» du problème pourrait simplement supprimer la plupart des paquets du système OP.

— Braiam

@Braiam Vous avez raison. Je tenais pour acquis que le package de suppression apt-get peut désinstaller des packages que le package d'installation apt-get ne restaurera pas nécessairement. J'ai édité, mais n'hésitez pas à le corriger si je ne suis toujours pas en ligne.
