Ca ressemble a un probleme avec une partie en C, nan ?
Naivement j'ai tente de desinstaller gimp, puis de relancer l'upgrade ... mais il y a un autre probleme avec un autre paquet ...
Bonjour,
Quel est l'autre paquet ?
Bonjour,
Je ne suis pas actuellement devant la station, mais il me semble qu'il s'agit de mavenv (enfin, je suis quasiment sur que c'est ce paquet 🙂.
J'aurai acces a la station demain matin.
Merci pour toute suggestion !
Bonjour,
Il s'agit plutot de maven !

# dnf list installed |grep maven
Ce qui est bizarre c'est que maven ne semble pas installe sur cette station ...

Bon il y egalement des problemes avec les import python sur cette station depuis l'upgrade (en fait je suis parti de fc27 si mes souvenirs sont bons). Je crois que suite a cette mise a jour c'est un peu le merdier dans la config ... Je vais deja regarder pour python et je regarderai ensuite pour les paquets geres par dnf. Toutes suggestions est bien sur bienvenue !
Bon pour python ca semble maintenant regle.
Je suis moins a l'aise avec les paquets systeme, donc comme la station semble tourner correctement par ailleurs et qu'il y a d'autres urgences a gerer pas sur que j'investisse beaucoup de temps sur cette histoire tant qu'il n'y aura pas de gros probleme ...
Il y a un moyen de nettoyer la config pour dnf ? J'ai essaye d'installer maven pour voir et ca installe des paquets qui sont, j'ai l'impression, pour fc29 alors que cette station est maintenant en fc30 ...
Y a des trucs zarrbi sur cette station ..

Modular dependency problem:

 Problem: conflicting requests
  - nothing provides module(platform:f31) needed by module gimp:2.10:3120191106095052:f636be4b-0.x86_64
Bon, j'ai pas eu le temps de tout lire et comprendre mais il semble qu'il y a un probleme sur cette station avec les modules, pour (seulement Ouf !) gimp et maven.
J'ai donc fait: 
# dnf module reset gimp
