At a moment, I have tried 'sudo herd trigger unattended-upgrade' whith no knowledge about the signification of 'trigger', lol... Then I realized that what I'd just done was to manually launch the update. A little later, I got confirmation that it had indeed taken place: $ guix system describe Génération 21 28 mars 2025 22:31:56 (actuelle) nom de fichier : /var/guix/profiles/system-21-link nom de fichier canonique : /gnu/store/pzb1xyi85y244wxcilg4a1bylz6lwmf0-system étiquette : GNU with Linux-Libre 6.13.8 chargeur de démarrage : grub-efi périphérique racine : UUID : e4fb3e05-b455-40db-bc59-4d4d011e1e01 noyau : /gnu/store/d7z9027yrs1vfmpvds10iqfl69cyvixn-linux-libre-6.13.8/bzImage canaux : guix: URL du dépôt : https://git.savannah.gnu.org/git/guix.git branche : master commit : b282b5ecd90da5dc3a034e7064ac41808f7f6c24 fichier de configuration : /gnu/store/8fn4ic4sir2p14fr3n67zzvbd6szaa7y-configuration.scm This morning, I can effectivitly boot with the new generation :) Thanks again for have help to clarify!
