Install CUDA on Ubuntu 20.04 driver version mismatch? CUDA: 465.19 Ubuntu:465.27

Do I need to uninstall the stock Ubuntu driver 465.27 and install the older 465.19 to be able to install/use CUDA?

I mean my system (after changing the Ubuntu default driver using the system options to the proprietary driver) is using version 465.27…

$ ubuntu-drivers devices
== /sys/devices/pci0000:00/0000:00:02.0/0000:03:00.0 ==
modalias : pci:v000010DEd00002503sv00001462sd0000397Dbc03sc00i00
vendor   : NVIDIA Corporation
driver   : nvidia-driver-460 - distro non-free
driver   : nvidia-driver-460-server - distro non-free
driver   : nvidia-driver-465 - distro non-free recommended
driver   : xserver-xorg-video-nouveau - distro free builtin

I’m on nvidia-driver-465 and I think this is the pertinent detail:
nvidia-driver-465/focal-updates,focal-security,now 465.27-0ubuntu0.20.04.2 amd64 [installed]

However, looking at the latest Ubuntu 20.04 options for CUDA: CUDA Toolkit 11.7 Update 1 Downloads | NVIDIA Developer the installer appears to want 465.19.

Thanks,

Looks like they’re from two different release branches, maybe the 465.27 (new feature branch) is backward compatible with 465.19 (beta)?

No. The driver specified in a given toolkit release is the minimum required and later drivers are required to be compliant with this Cuda version. So just skip the driver update part of the toolkit install.
