How I can update my nagios core 4.2.X version into latest version 4.3.X.?
I have installed the my nagios core in Ubuntu 16.06 LTS machine.Can anybody help me here.?

If you installed from source you can follow this guide
https://assets.nagios.com/downloads/nag ... ading.html

From package you would need to wait until the current package is available and then update the package

Hi scottwilkerson thanks for your help.

While upgrade the nagios I don't want to disturb my current setup.
Is it possible if I can upgrade the nagios without taking any downtime. ?

I am not in any position to guarantee no downtime, but if it is just upgrading source installs, the downtime between these versions should only be the time it takes to restart Nagios once the upgrade is complete.

One thing to note, if you use ndoutils as a Nagios addon (connections to mysql database) you would also want to upgrade that to it's latest as well

Okay I got it whatever you suggested to me but I am facing problem while running below mentioned command.

I have already checked that I have root user credential but while typing my password it says incorrect password.

Do you have any idea it is saying like that.?

command - su -l nagios

If you nagios user has a password set it may be asking for that, however..
I believe you can just skip that step and run the full procedure as the root user
