 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest
I’m not able to install the dependencies
e.g.
yum install perl-TermReadKey
Loaded plugins: fastestmirror, security
Setting up Install Process
Loading mirror speeds from cached hostfile
- epel: mirror.steadfast.net
 No package perl-TermReadKey available.
 Error: Nothing to do
New to centos and not sure what is missing. Can you please help?
