Downgrade XUbuntu kernel

Question

I'm now running XUbuntu 16.04 with kernel 4.4.0-31 and now I need to somehow downgrade kernel to version 4.1.24. Is there any way to do that?

Answer 1

Install required packages:

sudo apt-get install git fakeroot build-essential 
sudo apt-get install libssl-dev bc ncurses-dev xz-utils
sudo apt-get install kernel-package 

Download the Linux kernel

wget https://www.kernel.org/pub/linux/kernel/v4.x/linux-4.1.24.tar.xz
wget https://www.kernel.org/pub/linux/kernel/v4.x/linux-4.1.24.tar.sign

verify kernel signatures

unxz linux linux-4.1.24.tar.xz
gpg --verify linux-4.1.24.tar.sign

If you get "Bad signatures" try the following answer

tar xvf linux-4.1.24.tar
cd linux-4.1.24
cp /boot/config-$(uname -r) .config
make menuconfig

Make sure that the Enable loadable module support is selected.

Save and exit

Compile the kernel:

make-kpkg clean
fakeroot make-kpkg --initrd --revision=1.0.NAS kernel_image kernel_headers -j 16

Type the following command to find the .deb files:

 ls  ../*.deb

Install the kernel files:

sudo dpkg -i linux-headers-4.1.24_1.0.NAS_amd64.deb
sudo dpkg -i linux-image-4.1.24_1.0.NAS_amd64.deb

Reboot you system.

From the advanced option of GRUB, choose to boot the new kernel.

You can find the old kernel using the following command:

dpkg --list | egrep -i --color 'linux-image|linux-headers'

To remove it :

sudo apt-get --purge remove linux-imagexxxxx
sudo apt-get autoremove

Edit To solve this error unxz : linux : no such file or directory , install xz-utils :

sudo apt-get install xz-utils
