Comment 30 for bug 1930733

470 just got out of beta today: https://www.nvidia.com/Download/driverResults.aspx/177145/en-us

https://launchpad.net/ubuntu/+source/nvidia-graphics-drivers-470 shows in which repositories including PPAs it is available in. Currently only the beta is listed there.

And a bug to track the testing and releases should be listed on https://people.canonical.com/~ubuntu-archive/pending-sru.html soon.
