Error: Package: 1:control-center-2.28.1-39.el6.x86_64 (@server1)

You could try using --skip-broken to work around the problem You could try running: rpm -Va --nofiles --nodiges

It show after installing nux-dextop. I am using centos 6.6(64-bit). I am newly use centos. Thanks in advance.

Update : Solved :
In /etc/yum.repos.d/nux-dextop.repo file I made a small change. change the line enabled=1 to enabled=0. It shows no error.

thanks

Did you check in your nameserver /etc/resolv.conf

nameserver 4.2.2.1

nameserver 4.2.2.2

or

nameserver 8.8.8.8

or check to whether the repository URL ping your server.
