Error Installing Agent

[#1]

I am getting the below error while installing the agent. I am working on Ubuntu 20.04. It's a single machine cluster I want to make. Can anyone help me out with this?

Hello @avi_fcb  I can see it is failing with a permission denied error. Can you please check the permission on /tmp

Many thanks @Scharan . That was a permission error indeed.

But, after fixing this, I am getting this error "Monitor-HostMonitor throttling_logger ERROR Failed to collect NTP metrics". I have not installed NTP on my server. Do I need to ?? Do you have a any Idea??

Check this screenshot.

Hello @Scharan , I installed the NTP, but still the same error. 

Any suggestions on what went wrong?
