So the comments is this question Unable to get nvidia running on ubuntu 18.04.2 led me to this ask this one
When I did a fresh install of 19.04 (Kubuntu) I had to add the graphic driver ppa to install 430 as 418 is the highest one available in the official repos https://packages.ubuntu.com/search?suite=disco&arch=any&searchon=names&keywords=nvidia
I'm confused as to why the newer driver (and for that matter 435 which is in the ppa for 18.04) are not available in the newer version of Ubuntu, this seems kinda backwards to me. Is this an oversight or intentional?
Could someone "in the know" explain this to me?
the closest I could come to my question was Why are Nvidia proprietary drivers not visible on Ubuntu 19.04? but it doesn't quite address my question and also doesn't have an answer
Ubuntu 19.04 will reach End of Life in 3 months, so it makes no sence to update the driver in reposiroies. It is available in PPA.
You will be able to upgrade to 19.10 in a month or two, where you'll get the latest driver.
18.04 is LTS and will last for many years. That's why it got the update.
