We ran the validate and after verifying passwordless ssh it starts checking node1 for prereqs and hangs.
We enabled debug in the validate by uncommented the line
#set x
And ran it again, and we could see that it was passing
rpm -qa |grep ^dialog
And not getting a response.
Release : 21.2
Component : PERFORMANCE MANAGEMENT INSTALLATIONS/UPGRADES
There are 2 endpoint protection agents on these systems that can interfere with rpm commands
Tanium
xagt
The policy files for these end point agents contains rpm commands.
We needed to disable them to proceed with the install:
systemctl stop xagt
systemctl disable xagt
systemctl stop Tanium
systemctl disable Tanium
reboot
