Impossible de mettre à jour ubuntu 16.04 LTS à 18.04 LTS

Lorsque j'essaie de passer à Ubuntu 18.04 (à partir de 16.04 LTS) avec la commande:

Sudo do-release-upgrade -d

J'ai eu l'erreur suivante:

Checking for a new Ubuntu release

J'ai essayé de mettre à jour et de corriger manquant avec la commande suivante toujours le problème persiste

Sudo apt-get -f install

la sortie de lsb_release est la suivante

lsb_release -a

LSB Version:    core-9.20160110ubuntu0.2-AMD64:core-9.20160110ubuntu0.2-noarch:security-9.20160110ubuntu0.2-AMD64:security-9.20160110ubuntu0.2-noarch
    Distributor ID: Ubuntu
    Description:    Ubuntu 16.04.4 LTS
    Release:    16.04
    Codename:   xenial

comme suggéré ici J'ai modifié les caractères spéciaux dans /var/lib/dpkg/status mais le problème persiste.

Je pense que mon python a un problème lorsque j'essaie d'installer un paquet à partir de pip avec la commande suivante

pip install pyfaidx

J'ai une erreur similaire

Comment puis-je réparer le Python?

Edit-2 Problème résolu.

Réinstallez pip pip3 à partir des outils de configuration de pip installés source

pip install --upgrade pip setuptools
