For those who want to test the latest Linux kernels, Ukuu (Ubuntu Kernel Upgrade Utility) offers a simple interface with list of the “mainline” Kernels and allow user to one-click download and install a selected kernel release.
[ac-box style=”tip”]The mainline kernels are provided by Ubuntu Kernel Team for testing and debugging purposes. They are not supported and are not appropriate for production use. You should only install these if they may fix a critical problem you’re having with the current kernel. Read more about mainline kernels.
UPDATE 2020-08: UKUU is no longer free for use. You need to pay $12 for a personal license.[/ac-box]
