When you install the kernel, the following page ( https://www.debian.org/releases/jessie/i386/ch08s06.html.en) says you must run the following command: *​dpkg -i ../linux-image-3.16-subarchitecture_1.0.custom_i386.deb*. ​Do I need to run mrproper beforehand? I can't see any linux-image file in

Dear All, I am continuing the discussion of the kernel 4.14.15 compilation in the Question on CVE-2017-5754 on Debian 8.9 post in a new post. The reason I am running with this kernel and not the 4.15.0 rc9 kernel that is now available on kernel.org is that: 1. It is stable 2. I have never
