Hi,

I'm having an issue when installing Nagios XI on a new Ubuntu 22.04 LTS VM. There are a series of tests near the end (I assume) of the install process that fail, and the installation exits with the message "Subcomponents Installation failed -exiting". Without knowing what these tests are working on I'm struggling to diagnose the issue, I hope there is an obvious error in the log that I have missed!

For all support requests, we need to know:

Linux Distribution and version? Ubuntu 22.04 LTS
32 or 64bit? 64bit
VMware Image or Manual Install of XI? Manual Install
Are there special configurations on your system, ie; is Gnome installed? Are you using a proxy? Are you using SSL?

We do use a proxy for access to the internet. Its a "Ubuntu Server" install, so no DE. The VM is single use just for NagiosXI, but will have our Anti-Virus and Splunk installed

I've attached the install.log to the post.

Hopefully someone has seen similar before

. Additionally, is it best after a failed install to start again on a clean system, or can the install process be "recovered" on this existing system?

Thanks in Advance
Jim

Hi @jwalt, thanks for reaching out.

I am sorry to hear you are having issues. After a failed install it is always best to start again on a clean system.

What I am seeing in the install.log, is it is trying to install several packages, but running into prompts for "Proxy authentication" and appears to be failing, because it can not find Params::Validate, later on.

Code: Select all

Running install for module 'Params::Validate'

Proxy authentication needed!
 (Note: to permanently configure username and password run
   o conf proxy_user your_username
   o conf proxy_pass your_password
     )
Username:  
Password:  


Fetching with HTTP::Tiny:
https://cpan.org/authors/id/D/DR/DROLSKY/Params-Validate-1.31.tar.gz

Proxy authentication needed!
 (Note: to permanently configure username and password run
   o conf proxy_user your_username
   o conf proxy_pass your_password
     )
Username:  
Password:

Feel free to open a case with our support department at Nagios Answer Hub, for more assistance.

Hi Laura,

Thanks so much for your help. Looks like I will need to whitelist cpan.org domain and give this another go.

Do you happen to know if there is a documented list of external services thats required and should be whitelisted on proxies?

Thanks,
Jim

Hi Jim,

I don't believe we have anything documented that states what would need to be whitelisted, but looking through the install scripts, I don't see anything else that would be necessary on Ubuntu 22.

If you're seeing Nagios XI Installation Failed, it could be due to missing dependencies, permission issues, or incompatible OS versions. Ensure your system meets all prerequisites and that you’re using a supported Linux distribution. Try running the installer as root and check logs for detailed errors. Re-downloading the installer or updating your packages might help. If the problem persists, consult the official documentation or reach out to the Nagios support community for assistance. nulls brawl
