Ubuntu Software Center se bloque à cause d'une erreur dans son code Python
J'ai cherché cela, mais je n'ai trouvé aucune référence à cela sur ce site. Si vous en connaissez, référez-vous-y, les problèmes que j'ai vus présentent des symptômes différents. Donc, au point ...
J'ai longtemps eu Ubuntu 12.04 LTS, je suis passé à Ubuntu Gnome Shell, etc. Récemment, j'ai voulu passer à Ubuntu 13.04 et j'ai découvert un problème qui semblait s'être produit auparavant, mais à un taux apparemment aléatoire. Maintenant, je ne peux pas du tout démarrer le Centre logiciel Ubuntu.
Quand je lance la console, je vois:
$ software-center
(process:22270): Gtk-WARNING **: Locale not supported by C library.
Using the fallback 'C' locale.
Traceback (most recent call last):

J'espérais que suivre ces idées ( source ) pourrait être utile:
$ Sudo apt-get purge software-center
$ Sudo apt-get update
$ Sudo apt-get dist-upgrade
$ Sudo apt-get install software-center
$ Sudo dpkg-reconfigure software-center --force
Ce n'était pas:
$ Sudo apt-get purge software-center

Qu'est-ce que je fais mal? Comment puis-je me débarrasser de Ubuntu Software Center provoquant une erreur et installer une version qui n'en aura pas?
Ou peut-être que le problème vient de mon interprète Python?
$ python --version
Python 2.7.3
Je pense qu'Ubuntu se déplace progressivement vers des outils travaillant sur Python 3.x uniquement, mais est-ce la cause?
Merci pour tous les conseils. Je crois fermement que cela pourrait aussi être utile pour les autres.
Mise à jour 1 .:
La première mise à jour est passée de 12.04 à 12.10 et je n’ai pas remarqué qu’elle n’atteignait pas 13.04. Dès que j'ai remarqué, je suis passé de 12h10 à 13h04. Le problème n'a cependant pas disparu.
J'ai aussi fait ce que thefourtheye a demandé :
$ Sudo locale-gen

Et ceci est le résultat d'essayer de faire la purge:

Apparemment, les erreurs liées aux paramètres régionaux ont disparu, mais je ne parviens toujours pas à exécuter Ubuntu Software Center, même après une tentative de réinstallation.
Mise à jour 4 .:
Après en réinstallant quelques Python objets et en corrigeant l'ordre des classes de base pour SoftwareCenterConfig, j'obtiens ceci:

TL; DR:
Ce qui suit l'a corrigé pour moi:
Sudo chmod -r 755 /usr/local/lib/python2.7/dist-packages/
et
Sudo reboot
mon chemin de débogage
Je rencontre les mêmes problèmes avec Ubuntuone et Software-Center. Voici les étapes suivantes que j'ai entreprises pour poursuivre le débogage de ce problème:
U1_DEBUG=True /usr/lib/ubuntu-sso-client/ubuntu-sso-login
ce qui a conduit à la sortie suivante:
...
Traceback (most recent call last):
File "/usr/lib/ubuntu-sso-client/ubuntu-sso-login", line 67, in <module>
from ubuntu_sso.main import main
File "/usr/lib/python2.7/dist-packages/ubuntu-sso-client/ubuntu_sso/main/__init__.py", line 39, in <module>

File "/usr/lib/python2.7/dist-packages/twisted/__init__.py", line 40, in _checkRequirements
raise ImportError(required + ".")
ImportError: Twisted requires zope.interface 3.6.0 or later.
J'ai ensuite installé le zope.interface:
Sudo easy_install zope.interface
Je l'ai essayé dans l'interprète python:
>>> import zope.interface
et obtenu quelques erreurs "Permission denied" sur les packages Python:
IOError: [Errno 13] Permission denied: '/usr/local/lib/python2.7/dist-packages/httplib2-0.8-py2.7.Egg/EGG-INFO/top_level.txt'IOError: [Errno 13] Permission denied: '/usr/local/lib/python2.7/dist-packages/httplib2-0.8-py2.7.Egg/EGG-INFO/top_level.txt'
après quoi j'ai décidé de changer les permissions d'accès au fichier:
Sudo chmod -r 755 /usr/local/lib/python2.7/dist-packages/
ce qui a eu pour résultat que l'interface graphique d'Ubuntu One s'affiche et tente de se synchroniser. Seulement pour recevoir ensuite une exception dBus dans une fenêtre contextuelle. Au moins, l'interface graphique a commencé à fonctionner ...
Pour le centre logiciel, j'ai exécuté la commande suivante dans le terminal:
software-center --debug
un peu plus des mêmes exceptions dBus et googler le problème, j'ai découvert qu'un redémarrage suffit pour que les exceptions disparaissent qui sont déclenchées en raison d'un délai d'attente.
Il semble que votre /etc/environment ne contienne pas les paramètres de langue. Vous devez ajouter les lignes suivantes à /etc/environment:
