Package: linux-grsec Version: 4.8.15-2+grsec201701031913+1 Severity: grave Justification: renders package unusable
linux-compiler-gcc-5-x86 and linux-headers-4.8.0-2-common-rt are NBS and to be removed shortly. Once that is done, linux-headers-4.8.0-2-grsec-686-pae and linux-headers-4.8.0-2-grsec-amd64 will no longer be installable (which is definitely unusable).
