yum et le plugin yum-skip-broken
Par llaumgui le mercredi 28 février 2007, 14:00 - Linux - Lien permanent
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...

Je ne veux pas remettre en cause Yum je le trouve très bien ...
Mais je me met à côté d'un utilisateur qui débute il n'est pas simple.
Tu vas me dire qu'il existe l'interface graphique.
Et oui mais la dernière fois que je l'ai utilisé elle plantait.
Bref j'essayerais tes plugg et je te dirais quoi.

Le lien cassé vers l'article qui explique la lenteur de yum c'est fait exprès? ^^

Corrigé, merci

Bah, personellement, j'utilise toujours apt-rpm (ou plutôt "à nouveau", j'avais utilisé yum pour un certain temps entre l'arrêt des repositories apt-rpm classiques et l'ajout du support repomd à apt-rpm), il gère les repositories repomd (yum) maintenant (même si ça rame à peu près autant que yum, le vieux format était beaucoup plus rapide à parser), et les multilibs 64-bits aussi, et on n'a pas besoin de hacks comme yum-skip-broken, apt-rpm fait ça d'office.

C'est bon à savoir.
