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.

squashfs               98304  0

            @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

              # systemctl start snapd

                  et plus précisément, pas de message d’erreur ?
                  Vérifier que le module squashfs est bien chargé, puis relancer # systemctl start snapd et nous donner le retour

                  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
