I have tried to install nvidia driver for TU117GL [T1000 8GB] (rev a1) on my RHEL 8 platform without any success.
After installation when I run comand nvidia-smi It gives following output
NVIDIA-SMI has failed because it couldn’t communicate with the NVIDIA driver. Make sure that the latest N| 526 executing: '“/lib/modules/4.18.0-477.10.1.el8_8.x86_64/build/scripts/sign-file” “sha256” "/tmp/nvVIDIA driver is installed and running.
I am uploading debug report, Thanks in advance for any possible in this regard.

The driver installation was aborted:

Note that you will not be able to load the installed module until after a key that can verify the module signature is added to a key database that is trusted by the kernel. This will likely require rebooting your computer. (Answer: Abort installation)
ERROR: Unable to load the kernel module 'nvidia.ko'.  This happens most frequently when this kernel module was built against the wrong or improperly configured kernel sources, with a version of gcc that differs from the one used to build the target kernel, or if another driver, such as nouveau, is present and prevents the NVIDIA kernel module from obtaining ownership of the NVIDIA device(s), or no NVIDIA device installed in this system is supported by this NVIDIA Linux graphics driver release.

To me it looks like your kernel header versions are too old to compile the v525 kernel modules of NVIDIA. so it is likely you will need to update those first.

Plus, you will need to sign the module and after that reboot so that the signature can be properly added to the boot image.

This certificate must be added to a key database which is trusted by your kernel in order for the kernel to be able to verify the module signature.

This message indicates that either the reboot will initiate the new key to be added to some key database or that you will need to add it yourself. You should check Red Hat documentation on how to handle driver module signing.

I hope that helps.
