Fixed--cannot detect GPU

Scout — Wed, 30 Nov 2022 08:36:39 GMT

I have a PC and newly installed ubuntu 22.04. CLpeak reports no GPU. Below packages are installed:

intel-opencl-icd

intel-level-zero-gpu

Reading package lists... Done

intel-opencl-icd is already the newest version (22.43.24558).
You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
intel-level-zero-gpu : Depends: libigdgmm12 (>= 22.2.0) but it is not going to be installed
intel-opencl-icd : Depends: libigdgmm12 (>= 22.2.0) but it is not going to be installed
Depends: ocl-icd-libopencl1 but it is not going to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

Tried to install libigdm12, and it reported failure as below:
