Ubuntu Kernel Update Utility (Ukuu) v16.7

Ukuu v16.7 is now available. This is a major update which fixes all issues reported with the previous version.

 What's New 
  • Ukuu can now start in non-admin mode. It will prompt for the admin password before installing or removing a kernel.
  • Ubuntu's official kernels will also be listed. It will show all installed Ubuntu kernels with an option to remove them.
  • The notification functionality has been fixed. It will now display a notification dialog with an option to install the new update. The notification interval can also be selected as hourly, daily, weekly, etc.
  • Icons have been added to indicate the kernel type.

  1. I've heard that you should never manually update your kernel. Why would you want to do this?

    1. There is no need to update your kernel if your system is running fine. This tool is meant for experienced users who wish to try out the latest kernel.

      Linux has a very fast development cycle. While Ubuntu 16.04 shipped with v4.4 the latest stable kernel is v4.7. Every release of the Linux kernel includes security fixes, stability improvements, updated drivers and better performance.

  2. Is there a way to downgrade to an older installed kernel with UKUU? I can't see an option to do it. Thanks!!

    2. You should be able to install the older kernel with the tool, but to boot into it you need to use your bootloader to manage which Kernel to boot (i.e. Grub). For instance in Grub there should be an option such as "advanced boot options" listed somewhere below the default boot option along with the current Kernel recovery boot option. When you select this option, it will show a second menu with all of the kernels and their recovery boot options. I can't insert images, but just do a search for "grub advanced options for ubuntu" and some sites and/or images will come up.

    3. Keep pressing the up/down arrow when your pc boots to enter the grub boot menu. There will be a menu item for "advanced boot options" which will display a list of installed kernels. Select an older kernel and boot the system. Once the system is running, you can use Ukuu to uninstall the new kernel. Grub will automatically default to the latest kernel installed on the system on the next boot.

  3. Hello, Ubuntu Kernel Update Utility (Ukuu) v16.7 This is one of the most helpful, useful tools for Ubuntu I have come across. It works accurately & downloads & updates the kernel to the latest version. Not only that but it can safely remove the old kernel/s. Again it does this smoothly and can save you hours of messing around if your not familiar with using the command line. Highly recommend.
