Having difficulting installing local-built XRT with Ubuntu 22.04 kernel version 6.8.0-40-generic

[tjt7a]

I followed the build instructions for the 2023.2 branch of XRT and it compiled successfully. I then tried to install the Release version of XRT : sudo apt install ./xrt_202320.2.16.0_22.04-amd64-xrt.deb but ran into the following error:

tjt7a@puma:~/src/XRT/build/Release$ sudo apt install ./xrt_202320.2.16.0_22.04-amd64-xrt.deb

• DKMS failed to install XRT drivers.
• Please check if kernel development headers are installed for OS variant used.
• Check build logs in /var/lib/dkms/xrt/2.16.0

The kernel build log indicates that I may have an incompatible kernel version, but I figured the local build would have prevented this from happening. Any advice?
