Upgrading to a new kernel for Ubuntu Linux

We will need two things, a tar of the Linux kernel, and aunali1's linux-mbp-arch patches. The kernel can be downloaded from here. Make sure to get the right version for the current linux-mbp-arch version.

After downloading the kernel, we can start.

1. Make a folder for the Linux kernel and the patches to go into. For this guide, we'll make a folder in the home directory called kernel.
   • mkdir ~/kernel && cd ~/kernel
2. Move the Linux kernel archive to this new folder and extract it
   • mv /path/to/linux-[INSERT VERSION NUMBER HERE].tar.gz ~/kernel
   • tar -xf linux-[INSERT VERSION NUMBER HERE].tar.gz
3. Git clone the linux-mbp-arch repo to the directory where the kernel is located and change the directory to the Linux kernel
   • git clone https://github.com/aunali1/linux-mbp-arch.git
   • cd linux-[INSERT VERSION NUMBER HERE]
4. Manually apply the patches to the Linux kernel
   • for i in /path/to/linux-mbp-arch-master/*.patch; do patch -p1 --verbose < $i; done
5. Configure the kernel then compile it. This will take a while
   • Make sure you have libncurses-dev libssl-dev flex bison installed
   • make menuconfig
   • SAVE, OK, then EXIT
   • make -j8
   • sudo make modules_install -j8
   • sudo make install -j8
6. Make the kernel lighter, then update initramfs
   • sudo find . -name *.ko -exec strip --strip-unneeded {} +
   • sudo update-initramfs -u
7. Make sure the new initrd.img, vmlinuz, and config are in /boot
   • cd /boot && ls
8. Reboot your computer
   • sudo reboot
9. Verify the kernel upgraded successfully
   • uname -r If it reports the kernel you wanted to upgrade to, you are successful!
