cela veut dire que le module n’est pas chargé donc cela ne peut pas marcher.
# modprobe squashfs
Pour cela il fuat que kernel-modules soit installé
dnf list kernel-module* --installed
Il faut que le kernel-modules installé corresponde au kernel en service

    Aucun paquet correspondant à lister

    il faut installer
    # dnf install kernel-modules
    puis peut-être charge les modules, je ne sais si c’est fait à l’installation, le plus simple étant de redémarrer.

        @Hardelot , il y a du progrès ! je ne comprends pas pourquoi il n’a pas listé les kernel-mudules la première fois. Enfin squashfs est maintenant présent. Comme indiqué plusieurs fois il faut regarder dmesg(1) may have more information mais cela risque de me dépasser. J’espère qu’un pro prendra la main

        squashfs-tools est bien installé ?

          je viens de me rendre compte que ce n’est pas snap que j’ai utilisé pour HanBrake mais flatpack.
          N’ayant aucun logiciel sous snap, je fais snap install vivaldi et cela marche.
          Le débit pour vivaldi est trop lent pour ce soir, je l’ai interrompu ce qui explique l’erreur finale, le core s’est installé normalement

            et plus précisément, pas de message d’erreur ?

            c’est squashfs-tools et non juste squashfs qu’il faut installer

            activer un module ce n’et pas installer un paquet
            # lsmod | grep squashfs
            S’il n’y a pas de retour c’est qu’in m’est pas charger, pour le charger
            # modprobe squashfs
            refaire la vérification pour voir s’il est bien là,
            si oui vérifier l’état de snapd avec
            systemctl status snapd
            s’il est en ligne 5
            Active: inactive
            Alors essayer
            systemctl start snapd
            et nous donner le retour.

            Désolé mais cela ne sert à rien de faire des réinstalles, si on est pas assez clair, demander avant de taper à l’aveuglette

              j’abandonne mais une dernière fois…
              si squashfs est présent, il n’y a pas faire modprobe ! je croyais avoir été clair.
              Après avoir fait systemctl start snapd il aurait fallut refaire systemctl status snapd pour voir s’il est passé en actif
              Y aurait-il un problème avec Selinux, je vois qu’il y a un paquet snapd-selinux, est-il installé chez toi ?
              Je ne l’ai pas mais j’ai désactivé Selinux, c’est pas bien je sais

              10 jours plus tard

              Quand j’ai vu que cela ne fonctionnait pas je suis reparti à la 40 d’où mon silence et là, la 41… release installée, tout fonctionne.
