If you are Ubuntu users and wants to upgrade the Kernel, then follow the below instruction:
We will use Linux Kernel Utilities to upgrade Linux kernel
- compile_linux_kernel.sh
- update_ubuntu_kernel.sh
- remove_old_kernels.sh
Compile_linux_kernel.sh:- To compile and install the latest Linux Kernel from the source.
update_ubuntu_kernel.sh:- To downloads and install/update the already compiled Ubuntu Kernel.
remove_old_kernel.sh:- To removes all inactive and unused Kernels from the system.
Run the following commands to install Linux Kernel utilities in Ubuntu 20.04 LTS:
git clone https://github.com/mtompkins/linux-kernel-utilities.git
cd linux-kernel-utilities/
chmod 750 *.sh
git pull
Now, Run the following command to list the available Kernel.
./compile_linux_kernel.sh
Run the following command to compile and install the latest available Kernel:
./compile_linux_kernel.sh --latest
Run the following command to install precompiled Kernel:
./update_ubuntu_kernel.sh
To compile a kernel from a local archive file
./compile_linux_kernel.sh --archive=linux-4.5.2.tar.xz
It will list out the all available pre-compiled Linux Kernels from Kernel.ubuntu.com. You can see the number and you need to enter the desired number to install the selected Kernel.
Now restart your Ubuntu system.
Meanwhile, To download and install the latest a precompiled Ubuntu kernel from kernel.ubuntu.com, Run the following command:
./update_ubuntu_kernel.sh --latest
Now, Run the following command to remove old kernels.
./remove_old_kernels.sh
