Download
Before being able to install a new kernel in Ubuntu, the first thing you should do is download the kernel packages from the corresponding source. At this stage of the process, it is important to select the correct version of the kernel you want to install and download the necessary files for the installation.
You can find any version of the kernel at the following link:
- https://kernel.ubuntu.com/~kernel-ppa/mainline/
At this moment, the latest version of the Kernel is v6.2.14, therefore the download will be available at:
- https://kernel.ubuntu.com/~kernel-ppa/mainline/v6.2.14/
You must choose the appropriate version according to your PC's architecture, you can copy the download link, or download the files directly from the browser. I'll do it from the terminal, for version 6.2.14 I'll download the following files.
export WEB=https://kernel.ubuntu.com/~kernel-ppa/mainline/v6.2.14/amd64
export KERNEL=linux-headers-6.2.14-060214_6.2.14-060214.202305010032_all.deb
export GENERIC=linux-headers-6.2.14-060214-generic_6.2.14-060214.202305010032_amd64.deb
export MODULES=linux-modules-6.2.14-060214-generic_6.2.14-060214.202305010032_amd64.deb
export UNSIGNED=linux-image-unsigned-6.2.14-060214-generic_6.2.14-060214.202305010032_amd64.deb
wget $WEB/$KERNEL
wget $WEB/$GENERIC
wget $WEB/$MODULES
wget $WEB/$UNSIGNEDInstallation
Once the kernel files are downloaded, we can proceed to install them.
dpkg -i $KERNEL $GENERIC $MODULES $UNSIGNEDFinally, we must update the GRUB.
sudo grub-mkconfig -o /boot/grub/grub.cfg
update-grub
