I experienced a similar issue in Ubuntu 22.04 with a newer driver version. Please find the discussions & findings here: https://forums.developer.nvidia.com/t/unknown-error-from-cuda-11-7-ubuntu-22-04-64bit/220384/16
In a nutshell: Based on the modinfo output, nvidia as well as nvidia-uvm were signed with the same key but nvidia-uvm got rejected during secure boot, the other nvidia modules were loaded as expected. Disabling secure boot solves the issue but that's not the way it should be. I hope the info helps. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to nvidia-graphics-drivers-470 in Ubuntu. https://bugs.launchpad.net/bugs/1946312 Title: nvidia: Process '/sbin/modprobe nvidia-uvm' failed with exit code 1.
