[Gabriel]

Buenas a todos,

Estoy teniendo un problema con el yum que no me deja instalar nada:

Al parecer es un error que tiene que ver con la base de los rpm...
Ya intente hacer un rpmdb --rebuilddb pero sigue todo igual.
A alguien se le ocurre que puede llegar a ser esto y como resolverlo ??

Saludos y muchas gracias.
