Does this machine have an Internet connection? It looks like it is not able to reach out.

Also, please include the install.log file as indicated in the error output.

Hello Trevor,

Sorry, I didn't see your reply until now (I didn't get notification when response is posted. Just learned I can set the notification).
Yes, this machine has Internet connection. I can ping yahoo.com from this machine.

Hello,

Here is what I got for the curl command:

[ls4074@olph171 ~]$ curl -L -O https://assets.nagios.com/epel/epel-rel ... noarch.rpm

curl: (7) couldn't connect to host

however, On my pc, I could access the above URL.

Thanks!

OK, let us know if you still have install issues after confirming the machine has internet access. Please be sure to post the install log - thanks -

Hello,

The "curl: (7) couldn't connect to host" issue was caused by a proxy setting. I have fixed that. The install went quite a lot, but at the end, it gave errors. Please see the install.log in the attachment.

Thanks!

It looks like the proxy server blocked a file from being downloaded correctly.
We have a KB article for setting is a Nagios XI server for a proxy that you can use on the NNA server. Take a look at it and see if following through it, fixes the issue.

I have updated the /etc/yum.conf and /etc/wgetrc to use the http_proxy server. However, still get the error. Please see the install.log in the attachment. I am wondering if we can get the required rpm packages and we will install them separately before we run fullinstall.

Thanks!

The step that failed was: 'wkhtmltopdf'

I suspect that you have a few copies (some probably corrupted) of the "wkhtmltox-0.12.2.1_linux-centos6-amd64.rpm" package downloaded, i.e. "wkhtmltox-0.12.2.1_linux-centos6-amd64.rpm.2"... because initially you didn't have your proxy configured properly. Try installing the package manually by running the following command:
