Thank you for taking the time to report this issue and helping to make Ubuntu better.

Examining the information you have given us, this does not appear to be a bug report so we are closing it and converting it to a question in the support tracker. We understand the difficulties you are facing, but it is better to raise problems you are having in the support tracker at https://answers.launchpad.net/ubuntu if you are uncertain if they are bugs.

You can also find help with your problem in the support forum of your local Ubuntu community http://loco.ubuntu.com/ or asking at https://askubuntu.com or https://ubuntuforums.org. For help on reporting bugs, see https://help.ubuntu.com/community/ReportingBugs.

fyi: I have just installed 18.04(.3) a couple of times in the last 3-4 days and keyboard backlight worked on machines that had it, so it's likely an issue with your specific machine in my opinion. I think you are better served with a question which will provide help for you, instead of getting a problem fixed for future releases.

What's the model of your machine? Do you mind running 'sudo dmidecode' and post it to https://pastebin.ubuntu.com/?

or just:

sudo dmidecode -t 1

What is the output please?

Has the backlight ever worked?

Can you help with this problem?
