Lord d'essai pour installer un logiciel on m'a indiqué des lignes de programmation dans le terminal, ceci n'a pas fonctionné et j'ai laissé tomber l'installation de ce logiciel, mais ces lignes provoquent ces messages d'erreurs.
Merci pour tout.

The error in your log is:

/etc/kernel/postinst.d/zz-update-grub:

dpkg: erreur de traitement du paquet linux-image-4.4.0-145-generic (--configure) :

This indicates that you have manually installed the 'grub' package, which is not the recommended bootloader package in Ubuntu, and you have not configured it. As a result, upgrading kernel package afterwards results in an error.

To solve this issue you should remove the grub package from your system by running 'sudo apt purge grub'.
