Installing root CA certificates

I'm stetting up a testing environment. It's a closed environment with no access to the Internet when it's in use.

The environment is launched from AWS and consists of an Ubuntu 18 desktop and a Ubuntu Server running Apache. The desktop is able to successfully load the website, but with a cert error that the certificate isn't trusted.

When the Ubuntu Desktop launches, it has a fresh install of Firefox, and therefore all the directories in the users home folder are not yet setup for Firefox, including the database where the root CAs are stored.

I'm am able to add the Root CA certificate into the Firefox cert database AFTER the machine fully boots and I run Firefox for the first time. I'm using the 'certutil' package to do this. After I load Firefox, then add the root CA certificate using certutil, I'm able to load the website without error.

I need to add this certificate to the database with the startup shell script for the machine.

Any help is greatly appreciated. Here's the commands I'm using:

  1. copy the CA cert into firefox

export ffcerts=`ls /home/testuser/.mozilla/firefox/ | grep default-release` sudo certutil -A -n "testcert" -t "TC,," -i /home/testuser/certificates/testcertCA.pem -d sql:/home/testuser/.mozilla/firefox/$ffcerts

These commands work perfectly after Firefox is run for the first time. I've even tried adding 'Firefox' (with several different switches) into my startup script without success.

Thank you very much.

I'm generally a network engineer and not a sys-admin nor developer. I notice this is not so much a guide, but a detailed reference for an experienced user.

I'll do my best to make sense of it, and do some searches to see if I can learn how to apply this correctly. If there is a guide on how to implement this, I'd be very grateful.

There is a policy available to install a certificate.

Thanks. After parsing through the information I was able to successfully add my certificate.

thank you.

Also post that to a Ubuntu forum as well since that could be O/S related.
