How do you install test kernel? I tried dpki -i linux-modules-4.15.0-24-generic_4.15.0-24.26+crng4_amd64.deb linux-modules-extra-4.15.0-24-generic_4.15.0-24.26+crng4_amd64.deb linux-image-unsigned-4.15.0-24-generic_4.15.0-24.26+crng4_amd64.deb
but I get error: Preparing to unpack linux-modules-4.15.0-24-generic_4.15.0-24.26+crng4_amd64.deb ... Unpacking linux-modules-4.15.0-24-generic (4.15.0-24.26+crng4) over (4.15.0-24.26+crng4) ...
