J'ai trouvé un problème et sa solution, j'ai pensé que ça pourrait être utile à d'autre...

Depuis hier soir j'ai ça :
]# yum upgrade
Modules complémentaires chargés : allowdowngrade, downloadonly, filter-data, keys, list-data, refresh-packagekit, remove-with-leaves,
: tmprepo, verify
Traceback (most recent call last):

J'ai désinstallé yum-plugin-tmprepo et plus de problème (rpm -e yum-plugin-tmprepo).
Si je le réinstalle ça rebug.
Bref c'est un peu cassé.
