Re: Unable to build kernel module on v190->260 on last few major kernel revisions
Mmm.. the first error in the nvidia log you posted was "ERROR: Kernel configuration is invalid.". So the installer is having trouble recognizing or finding your configured kernel source tree.
If you can get over that hump, then rest assured it does build (and run) with the latest 18.104.22.168 kernel, and earlier ones too.
Is that really Con ?
