Manual kernel installation on Debian

Recently I had to manually install kernel on one Debian machine. Steps are as follows:

• Download kernel-headers and kernel-image deb packages
• Install these packages with

dpkg --force-architecture --force-overwrite --install

• Still we are missing initial RAM disk and this one can be created with mkinitramfs:

mkinitramfs -o initrd.img-<kernel_version>-deb-32 <kernel_version>-deb-32

• After this step RAMdisk will appear in /boot:

initrd.img-<kernel_version>-deb-32

• Update grub and check /boot/grub/grub.cfg to verify that new entry is added:

update-grub
