Delta RPMs disabled because applydeltarpm not installed

Originally published at: https://www.cyberciti.biz/faq/delta-rpms-disabled-because-applydeltarpm-not-installed/

I getting the following warning on both CentOS 7 and RHEL (Red Hat) 7 when I run :
Delta RPMs disabled because /usr/bin/applydeltarpm not installed.
What is delta RPM (DRPM) and how does it differ from RPM? How do I fix this issue on a CentOS or RHEL 7 server/desktop?

I am seeing this error on a VM disconnected from the internet. I put the deltarpm package on the VM tried to install but I am getting the same error: Delta RPMs disabled because /usr/bin/applydeltarpm not installed.
This is seeming to be a loop. Any ideas how i can overcome this?

You need to install that package either from the Internet or CD/DVD rom.
