Problem in install(xocl, xclmgmt andERT firmware)

Reproduce the Ubuntu 22.04 installation using build.sh and the generated xrt*.deb, then inspect the DKMS installation output and /lib/firmware/xilinx. Determine whether the xocl and xclmgmt messages, Secure Boot notice, and missing ERT firmware are expected. Done means documenting the cause and required installation steps, or identifying a reproducible packaging defect.

I run in ubuntu22.04: Follow the instruction in https://xilinx.github.io/XRT/2022.2/html/build.html
When : sudo apt install ./xrt_202220.2.14.0_22.04-amd64-xrt.deb

There is some problem in xocl and xclmgmt, and also I see "Secure Boot not enabled on this system."
and ERT firmware seems to be skipped, I can't find it in /lib/firmware/xilinx.

Could you tell me is my installation successful? How can I solve these problems?

The follow result is:

sudo ./build.sh 
****************************************************************
* XILINX_VITIS is undefined or not accessible                  *
* MicroBlaze firmware will not be built                        *
****************************************************************

Above is some warnings? But the build.sh is success and package the xrt*.deb

sudo apt install ./xrt_202220.2.14.0_22.04-amd64-xrt.deb
