arria-10-gx dev ttack won't install on x86_64

so far I am interested to confirm that the card just works e.g. with the most tiniest hello world example or another diagnostic test if possible

any directions here? I was looking previously in

https://www.intel.com/content/www/us/en/docs/programmable/683633/1-2-1/running-the-hello-fpga-example.html

with https://www.intel.com/content/www/us/en/software-kit/665840/intel-pac-with-intel-arria-10-gx-fpga-acceleration-stack-version-1-2-1.html

but it would say PAC not detected on ubuntu 18/20

on executing

sudo fpgasupdate $OPAE_PLATFORM_ROOT/hw/samples/nlb_mode_0/bin/\
nlb_mode_0_unsigned.gbs

despite showing lspci outputs
