Impossible de passer de 16.04 à 18.04, aucune erreur réelle?

J'ai reçu l'avis de mise à jour pour l'installation de mon bureau, mais je ne peux pas le faire. Je ne vois aucun message d'erreur réel. J'ai exécuté Sudo apt autoremove, Sudo apt upgrade et Sudo apt install, et cela donne 0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded. Ceci est mon écran lorsque je lance do-release-upgrade:

Ubuntu a cessé de prendre en charge les systèmes de bureau 32 bits à compter de 17h10. La dernière version de 32bit est 16.04.5, par https://www.ubuntu.com/download/alternative-downloads .

essayer:

Sudo apt-get install lsb-core

puis mise à niveau

Parfois, ce paquet est manquant ou corrompu et le programme d'installation a du mal à déterminer quelle version est en cours d'exécution. Il y a beaucoup de plaintes à ce sujet si vous le recherchez sur Google. La même chose pourrait arriver dans Debian.
