yum et le plugin yum-skip-broken

llaumgui — Wed, 28 Feb 2007 14:00:00 +0100

De plus en plus yum subit les critiques :

On lui reproche d'être trop lent : à cela il y a une explication.
On lui trouve des remplaçants.
Certains même regrettent le temps de FC3 où apt-get régnait en maître sur la gestion des RPMs.

Je suis pas d'accord avec cette vision, je pense que yum et l'un des gestionnaires de paquet les plus puissants. Il gère le multi-architecture (x86 sur du x86-64), ce qu'apt-get ne fait pas encore. Mais surtout, les fonctionnalités qui lui manquent peuvent être rajoutées via des plugins.

Et c'est justement de plugin que je vais parler dans ce billet, le plugin yum-skip-broken.

Prenons l'exemple d'une mise à jour via yum qui ne peut satisfaire toute les dépendances :

root@enterprise ~> yum update

Deux solution s'offrent à nous :

La première étant de jouer avec le flag --exclude
La seconde consistant à utiliser le plugin yum-skip-broken.

Installation du plugin :

root@enterprise ~> yum install yum-skip-broken

Mise à jour en utilisant le plugin :

root@enterprise ~> yum update --skip-broken

Is this ok [y/N]:

C'est pas plus dur que ça et cela évite d'utiliser --exclude, de faire un essai, de rajouter un autre paquet dans la liste des paquets exclus, refaire un essai, etc...
