Package issues

[webies]

Hello

Recently I've been trying to setup an RDP in my server but things didn't works as expected so I removed the package that I've installed

but now, when I run yum update I get the follow error:

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

How can I fix this?

thank you

You've got conflicting versions of the repos installed. Some of those packages have .el6. in their names, others have .el7. indicating that they are for CentOS 6 and 7 respectively. You cannot install el7 packages on el6 or vice versa. You need to determine which version of CentOS you have installed (rpm -q centos-release) and then uninstall the repo which is not for your version. Once uninstalled, install the correct version of the repo and run yum clean all to clean up the old invalid metadata and try again. Also, check your installed packages to make sure you don't have anything for the wrong version installed - so on CentOS 6 run rpm -qa | grep el7 and then find el6 versions of any packages that are listed. If you're on CentOS 7 then reverse that and grep for el6.
