Waiting for configuration verification... .
Backend login to the Core Config Manager failed.

Please help.

Are you using a proxy on your installation?

Hi,
Yes I am. I am using the VMWare appliance and it has been working without any issues. I did however upgrade to the 1.8 release recently.
Thanks

There have been repo changes for CentOS 6, so our FAQ solution may not work for proxy installations on CentOS 6. If I were to guess, I would bet that you're missing the following package, and you'll have to figure out how to get it installed through your proxy.
php-pear-HTML-Template-IT.noarch
You can check if it got installed by running:

Thanks for your reply.
I do have it installed. the results from the command is below.
php-pear.noarch 1:1.9.0-2.el6 @base
I would like to point out though that the installation has been working fine without any issues prior to the upgrade to version 1.8.
Any assistance is appreciated. Going LIVE soon so very important to resolve this issue.

This issue mirrors this thread:
http://support.nagios.com/forum/viewtop ... f=6&t=4129
Pear is installed, the pear templating package is missing:
Code: Select all
[root@localhost ~]# yum list installed | grep pear
php-pear.noarch 1:1.9.0-2.el6 @base
php-pear-HTML-Template-IT.noarch
If you can figure out how to install
php-pear-HTML-Template-IT.noarch from behind a proxy, go ahead and post the solution and we'll update our wiki. I'm betting that if you can get that installed, then run the installer again with a
freshly unzipped tarball, I'm betting that you'll be able to get the installer to work.

Just to clarify issues here. My NagiosXI VM had been working prior to installing the 1.8 upgrade. I have hosts configured on this box without any problems. I now cannot add additional hosts.
Do you know why this would have suddenly stopped working?
I'm thinking of starting all over again but I do not have any gurantees that this issue will re-appear after anther successful deployment.

Ok, sorry for the confusion, I thought this was a new install, not a freshly upgraded install.
Can you post your output from the instructions in the following wiki:

Can somebody help with this? We cannot add any hosts at present for the Nagios system which is due to go live next week.
