it does not work with Ubuntus hwe (hardware enabled) kernel, which is currently 5.15. If you uninstall the hwe components and just install linux-image-generic and linux-headers-generic it works (kernel 5.4)

Hi.
Would you be able to provide more detailed instructions or maybe relevant links? I have never done it and at this moment have no idea how this can even be done. I am using Google Cloud VMs, if it matters.
Thank you.0 -
I executed these commands to use an older kernel:
wget https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.4.230/amd64/linux-modules-5.4.230-0504230-generic_5.4.230-0504230.202301240741_amd64.deb wget https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.4.230/amd64/linux-image-unsigned-5.4.230-0504230-generic_5.4.230-0504230.202301240741_amd64.deb sudo dpkg -i linux-modules-5.4.230-0504230-generic_5.4.230-0504230.202301240741_amd64.deb sudo dpkg -i linux-image-unsigned-5.4.230-0504230-generic_5.4.230-0504230.202301240741_amd64.deb
Hope it helps.

Good to know, thanks.
Though I abandoned the LF course. I will do Udemy instead and only the certification with LF.0
