The blender version above is the one installed using apt-get. I downloaded however the most recent release, this is the correct info:

The issue might be the graphics drivers installed. If I recall correctly, OpenCL isn't available with just Mesa graphics. Maybe you can find some help here? https://devtalk.blender.org/t/guide-install-amd-opencl-on-pop-os-some-ubuntu-derivates-linux-amdgpu-amdgpu-pro-rocm-rocr/13458

As a side note, we only officially support versions of Blender installed from official sources. They can be found on the Blender website: https://www.blender.org/download/

Although Blender is available from your distributions repository, it is not officially supported.

I think you are right upon OpenCL. clinfo give me: numbers of platforms 0. I think this means OpenCL is not available. correct ?
BTW I have the most recent official release of blender from blender.org.

The devtalk is not very easy to understand, furthermore I would not be very happy if my system would not boot any more ...

That is correct, this is either due to the integrated GPU not being powerful enough or you need to install official drivers, see https://docs.blender.org/manual/en/latest/render/cycles/gpu_rendering.html#amd
