[OpenIndiana-discuss] Fresh install of OpenIndiana - can not upgrade nvidia from nvidia-390 to nvidia-460

[russell]

Hi

My dual opteron motherboard finally died, so I had to build a new 
workstation based on a Ryzen 5 5600X.
Once the workstation was built, I started the Openindiana install, 
downloading the 2020 October text based iso.
Very happy with the installation, no problems there as I wanted to 
create a mirrorred boot pair of SSDs.
After completing the Openindiana install on the mirrored pair, I 
performed a pkg refresh, then a pkg update creating a new BE.
After completing the update and I performed pkg install mate_install it 
worked fine, though I have noticed a couple of things.

1) when performing a pkg install/update the create plan can take a very, 
very long time compared to the Dual Opteron 2435 workstation.
      Things that took seconds or worse a few minutes can now take 
hours...(literally being left over night)

2) When I attempted to replace the Nvidia-390 driver with the Nvidia-460 
driver, by removing the Nvidia-390 driver it has a dependency on nvidia 
pkg, attempting to remove nvidia pkg results in a warning that the mate 
install depends on pkg nvidia.

How can upgrade to the Nvidia-460 driver?

Regards

Russell
