Greetings,
Can anyone help me on how to fix this problem?
when i run yum update from CLI i got this one

[root at ict ~]# yum update
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
 * base: sunsite.rediris.es
 * extras: sunsite.rediris.es
 * updates: sunsite.rediris.es

---> Package python-libs.x86_64 0:2.4.3-44.el5_7.1 set to be updated
http://mirror.centos.org/centos/5/addons/x86_64/repodata/filelists.xml.gz:

Error: failure: repodata/filelists.xml.gz from addons: [Errno 256] No more
mirrors to try.
 You could try using --skip-broken to work around the problem
 You could try running: package-cleanup --problems
                        package-cleanup --dupes
                        rpm -Va --nofiles --nodigest


>From there i tried those options but still i cant update.

Centos 5.5
