I can't install control panel because yum update failed. I use centos7. Please help me…. What should I do?

[root@trial ~]# yum

Resolving Dependencies
There are unfinished transactions remaining. You might consider running yum-complete-transaction, or "yum-complete-transaction --cleanup-only" and "yum history redo last", first to finish them. If those don't work you'll have to try removing/installing packages by hand (maybe package-cleanup can help).
The program yum-complete-transaction is found in the yum-utils package.

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

If you check your error message, you'll see that update packages contains el6.x86_64 prefix, that rpm package for CentOS 6. Looks like you install EPEL for CentOS 6. Remove wrong repo(for example, rpm -qa | grep epel | xargs rpm -e or rm /etc/yum.repos.d/epel*.repo if you install it manually), run yum clean all, install right EPEL trough yum install epel-release and try to run yum update again.
