Manually Upgrade Linux Kernel, Pop!_OS
Upgrading the Linux Kernel manually is simple!
Download Kernel
Find the Kernel you want at the
kernel-ppa and download the
.deb-files of interest (4 in total).
If you are reading this article, you want to download:
linux-headers-*_all.deb
linux-headers-*generic*_amd64.deb
linux-image-unsigned-*_amd64.deb
linux-modules-*_amd64.deb
For instance, if you want to download the Linux 5.6 Kernel, the files are:
linux-headers-5.6.0-050600_5.6.0-050600.202003292333_all.deb
linux-headers-5.6.0-050600-generic_5.6.0-050600.202003292333_amd64.deb
linux-image-unsigned-5.6.0-050600-generic_5.6.0-050600.202003292333_amd64.deb
linux-modules-5.6.0-050600-generic_5.6.0-050600.202003292333_amd64.deb
Put them all somewhere nice, like in: ~/Downloads/5.6.0/
Install Kernel
It’s as simple as running sudo dpkg -i *.deb in whichever directory you chose
to put your .deb-files.
Make the Kernel bootable
If you are using grub, I think all is fine here, but I’m running
systemd-boot so according to
Frank there
are some extra steps. Head over to his site and read from Copying the installed
kernel to make it bootable and down.
