Hello,

You'll need to add the EPEl repo and then try installing the requirements again. If you get any errors, post them to the thread.

See: https://fedoraproject.org/wiki/EPEL

One of the configured repositories failed (Unknown),
and yum doesn't have enough cached data to continue. At this point the only
safe thing yum can do is fail. There are a few ways to work "fix" this:

1. Contact the upstream for the repository and get them to fix the problem.

2. Reconfigure the baseurl/etc. for the repository, to point to a working
upstream. This is most often useful if you are using a newer
distribution release than is supported by the repository (and the
packages for the previous distribution release still work).

3. Run the command with the repository temporarily disabled
yum --disablerepo=<repoid> ...

4. Disable the repository permanently, so yum won't use it by default. Yum
will then just ignore the repository until you permanently enable it
again or use --enablerepo for temporary usage:

yum-config-manager --disable <repoid>
or
subscription-manager repos --disable=<repoid>

5. Configure the failing repository to be skipped, if it is unavailable.
Note that yum will try to contact the repo. when it runs most commands,
so will have to try and fail each time (and thus. yum will be be much
slower). If it is a very temporary problem though, this is often a nice
compromise:

yum-config-manager --save --setopt=<repoid>.skip_if_unavailable=true

Something is wrong with your repos. Are you using a proxy and/or custom repos? Here's a list of repos from a "vanilla" RHEL 7 system with Nagios XI installed on it:
Try running: Do you see any errors?

Hi Team,
Can some one help me with cpanm issue.
Iam trying to execute the command cpanm --notest Module::Build Crypt::SSLeay but throwing error.

we are in an OFFLINE environment and are using a CPAN replicated Mirror.

Unfortunately, this is not something that we would support. We don't know how you have your CPAN replicated Mirror set up, how often you are updating it, if you are using instant mirroring, etc. You will have to talk to your system administrator, and find a way to install all of the required packages in your specific environment.
