Saludos EPE, gracias por tu respuesta, la verdad es que no lo puse yo, yo tengo en el cron que se actualice por si solo en un determinado tiempo, cada mes, y como vi una nota que ya salio el CentOS 5.1 queria actualizarlo yo mismo, y cuando intento hacerlo me sale eso, yo no puse eso, y verifique los repos y supuestamente todo esta bien, no se que mismo paso, la última actualización que hice fue del squid, y solo instale el Nagios desde el repo de DAG, y de ahi solo tengo activado los repos de CentOS, ningún otro repo lo tengo en "/etc/yum.repos.d" más que los de CentOS, y por más que quiero no me instala, y no actualiza nada de nada, esto es lo que tengo en "
CentOS-Base.repo" de ahi, no acostumbro a modificar nada en los repos del CentOS:<br><br># CentOS-Base.repo<br>#<br># This file uses a new mirrorlist system developed by Lance Davis for CentOS.<br># The mirror system uses the connecting IP address of the client and the
<br># update status of each mirror to pick mirrors that are updated to and<br># geographically close to the client. You should use this for CentOS updates<br># unless you are manually picking other mirrors.<br>#<br># If the mirrorlist= does not work for you, as a fall back you can try the
<br># remarked out baseurl= line instead.<br>#<br>#<br><br>[base]<br>name=CentOS-$releasever - Base<br>mirrorlist=<a href="http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os">http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os
