UKUU 20.05

UKUU v20.05 is now available

What’s New

Secure Boot Warning

Since the mainline kernels are unsigned, they cannot be used if Secure Boot is enabled on your system. Installing unsigned kernels on such a system will fail with an error.

A warning will now be displayed if Secure Boot is enabled and you try to install a unsigned kernel. You can turn off this warning from the Settings window.

Refresh button

A Refresh button has been added to main window. It will clear the app cache and fetch list of available kernels from Ubuntu server.

I’m adding this button as many people have asked for it. There is almost no reason to have this button, as new kernels are normally released once a week, and Ukuu checks for new kernels automatically. It is useful in the rare scenario when you are having network issues and if the list is not updated for some reason.

Basic support for other kernels

In previous versions, the app could be used only if the active/running kernel was of a known type (official or mainline). If you were running some other kernel and it was unable to determine the type, then it would refuse to start.

Ukuu can now recognize kernels of some other types (xanmod and liquorix). Installing and removing these kernels is not supported, but installed kernels will show up in the list. If the active kernel is of unknown type then the app will start, but it will skip any actions that can cause problems (automatic updates, etc).

Other kernels will be displayed with a yellow icon.

Misc

  • Clicking the Settings button will open a new window instead of displaying options in the same window. This fixes an issue with window resizing.

Purchase

A personal licence for Ukuu is currently available for $15. This is a single-user licence that is valid for lifetime, and includes future updates.

Buy Licence

Install / Update

You will receive an email with installation steps after you purchase a licence.

If you have already installed the app, the update will install automatically when you update your system. You can install it manually with following commands:

sudo apt update && \
sudo apt install ukuu ukuu-gtk

  1. I purchased a UKUU license from you back in late Dec 2019.
    Wonderful investment; you make a great application. Thanks for your hard work

  2. Hello,

    I just bought a licnese.
    However, ukuu doens’t install modules.

    I use vfio and vfio-pci.
    A modinfo check on those modules shows that they are not installed after booting into 5.4.x.

    This is a game stopper for me.

    What can I do to fix this?
    thanks

    1. Xanmod and Liquorix provide a repository for Debian/Ubuntu. A tool like Ukuu is not useful for these kernels.

    1. There are no plans currently. Systemd-boot is still very new and as far as I know there is only one Ubuntu-based distribution that is using it (Pop OS). The mainline packages provided by Ubuntu depend on GRUB being the default boot loader.

  4. I can see my installed liquorix kernels but not the xanmods. Also, liquorix kernels show up out of order since they put an extra zero in the version number. For example, there version 5.7.0.4.1 kernel is really 5.7.4.1 kernel. I don’t know if you can fix these issues. Love your program. Licensed user of one year.

      1. Hi Jens… If you need support please send me an email instead of leaving a comment. If someone leaves a comment I have no way to verify who the person is.
        Latest version of this app is v20.06.2. Upgrade to this version and click Refresh button on the main window. This will solve the problem.

  6. Hello Tony, I have 4 Servers. Running Debian, Ubuntu. and CentOS. Can you please let me know if I can get a license copy that I can run on the four servers? Please keep the pricing cost effective since I am from India and the conversion rates are high.

    1. You can use a single licence on all your servers as long as you are the primary user.

      These mainline kernels are not meant to be used on servers/production systems as updating the kernels can sometimes cause problems. Stick to the official kernels for better reliability on servers.

  7. Feature request: Being able to set a random already installed kernel as active kernel for next boot. Sometimes have to roll back from latest to previous because of driver support not yet there. Now its a hassle to do that
