How to install perl in RHEL 7?

Question

I use RHEL 7.2 and want to install perl. Executing yum install perl, it outputs the following:

# yum install perl
......
Total size: 11 M
Total download size: 8.0 M
Installed size: 36 M
Is this ok [y/d/N]: y

Error downloading packages:

  4:perl-5.16.3-286.el7.x86_64: [Errno 256] No more mirrors to try.

I have tried yum --enablerepo=rhel-7-server-rpms clean metadata, but the result is same. How can fix this issue to install perl successfully on RHEL 7?

Solution

Just executing yum clean all:

yum clean all

Then this issue is solved.
