14.04.4 LTS à 16.04.3, mise à niveau de LTS - ImportError: aucun module nommé 'lsb_release'

S'il vous plaît j'ai besoin d'aide, je connais à peine et très nouvel utilisateur Ubuntu. J'essaie de passer de 14.04.4 LTS à 16.04.3 LTS en utilisant

do-release-upgrade

mais il échoue et j'ai eu ce message d'erreur

    Traceback (most recent call last):

Que dois-je faire pour résoudre le problème de la mise à niveau complète?

Merci d'avance.

J'ai cherché le module lsb_release avec dpkg -S lsb_release | grep python sur mon Ubuntu 16.04.3 LTS et ai obtenu son paquet (lsb-release). Dans Trusty, il se trouve dans le même package .

Donc, pour moi, il semble que vous devriez installer ce paquet avant de mettre à jour avec
Sudo apt-get install lsb-release.
