[root@host-192-168-1-2 ~]#
j'imagine que ton système est à jour ? Le cas échéant, as tu tenté un dnf distro-sync ? Je propose un peu au hasard, faute de mieux...

en fait j'ai l'impression qu'il y a 2 types d'erreurs, d'une part celle-ci : 
nothing provides libXfont2.so.2()(64bit) needed by xorg-x11-server-Xwayland-1.19.0-0.8.rc2.fc25.x86_64.
ça pourrait s'expliquer par un problème temporaire sur les dépots F25 ;

et de l'autre celle-là : 
package foomatic-4.0.12-7.fc24.x86_64 requires perl(:MODULE_COMPAT_5.22.2), but none of the providers can be installed.
et ça je pense qu'un distro-sync peut les résoudre.
Bon, j'ai fait un dnf distro-sync , ce qui m'a retrogradé une centaine de paquets (que j'avais surement installé avec updates-testing), mais pas d'amélioration :

De plus j'ai perdu mes drivers nvidia, mais je verrais plus tard avec la F25.

Je pense qu'il y a un soucis avec les dépôts, qui ne doivent pas être entièrement peuplés.

Je vais donc attendre encore un peu.

Je pense aussi. C'est quasi toujours le cas dans les premiers jours de sortie d'unenouvelle Fedo.
Je me donnerais des baffes...
Le problème est que j'avais désactivé le dépôt fedora, et oublié de le ré-activer.
C'est parti pour un téléchargement d'environ 2600 paquets (2.5 Go).
Je posterai le résultat dans la section "Fedora 25 - retour d'expérience"
Bien vu, je n'y avais pas fait attention. A force de rechercher des dépôts exotiques on passe à côté des choses simples.
Faut dire aussi que d'aller désactiver le dépôt principal faut être chaud patate 😉

Ben oui, chepioq, pourquoi avais tu désactivé le dépôt fedora ?

Je l'avais désactivé il y a quelque jours car il me mettait une erreur lors des mises à jour (en gros "impossible de récupérer les metadatas pour le dépôt fedora").
Je n'avais laisser que le dépôt fedora-updates activé.
