Bonjour,
Je n'arrive pas à mettre à jour ubuntu. Voici ce que j'obtiens lorsque j'utilise sudo do-release-upgrade :

Recherche d'une nouvelle version d'Ubuntu

Error in sys.excepthook:

    (result, consumed) = self._buffer_decode(data, self.errors, final)

Original exception was:
Traceback (most recent call last):
  File "/tmp/ubuntu-release-upgrader-c9ylfzr9/disco", line 8, in <module>
    sys.exit(main())
  File "/usr/lib/python3/dist-packages/DistUpgrade/DistUpgradeMain.py", line 238, in main
    if app.run():

    return self.fullUpgrade()
  File "/usr/lib/python3/dist-packages/DistUpgrade/DistUpgradeController.py", line 1906, in fullUpgrade
    if not self.askLivepatch():
  File "/usr/lib/python3/dist-packages/DistUpgrade/DistUpgradeController.py", line 1175, in askLivepatch
    version = next((r.version for r in di.get_all("object") if r.series == self.toDist), self.toDist)
AttributeError: 'UbuntuDistroInfo' object has no attribute 'get_all'

J'ai l'impression qu'il y a un problème avec python mais je ne sais pas du tout quoi faire.

Merci pour votre aide.
