J'ai installé le noyau principal 4.18 à partir d'ici http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.18/ en utilisant ubuntu 18.04
Les packages ne sont pas signés et grub s'en plaint à chaque mise à jour.
E: Your kernels are unsigned. This system will fail to boot in a secure boot environment.
Comment puis-je faire disparaître le message? Ou faire signer 4.18?
Je ne cherche pas à construire mon propre noyau.
J'ai fini de revenir au noyau par défaut d'ubuntu et tout fonctionne comme prévu.
Mon processus pour supprimer le noyau non signé (oublié que je l'avais installé?):
