UKUU 22.01 is now available.
What’s New
libssl3 dependency
The latest builds of Mainline kernels on Ubuntu’s Mainline PPA server are built against libssl3. This package is available only on Ubuntu 22.04 (Jammy Jellyfish) which is yet to be released (in April 2022). This package has been added to UKUU’s repository so that mainline kernels can be installed on older versions of Ubuntu.
Better detection of kernel flavors
The detection of other kernel flavors (aws, azure, gcp, gke, oracle, kvm, etc) for official (Ubuntu) kernels has been improved. Hovering the mouse over an installed kernel will display the type (Ubuntu, Mainline, Xanmod, Liquorix), the flavor (generic, lowlatency, aws, oracle, etc), and the list of installed packages.
The status bar now shows the flavor and type of kernel on a separate line.
The list of unused kernels now shows more information about the flavor and type of kernel.
Removing Official Kernels
Some warnings have been added for actions that are potentially dangerous.
A warning will be shown if you try to remove all official kernels. You can ignore this and continue at your own risk. On some Ubuntu-based distributions, you can safely remove all official kernels and keep only mainline kernels. On other distributions, removing all official kernels will either break your system (due to package dependencies) or cause other problems.
For safety, the latest official kernel will remain unselected by default in the GUI list. You will get the warning only if you explicitly select all kernels for removal.
Misc
- Fix: Use ‘apt-get’ to remove packages instead of ‘dpkg’. This will resolve any dependency issues caused by removal of packages.
- Fix: Incorrect status is sometimes shown if package installation/removal fails
- Fix: Add more checks to prevent removal of last-remaining official kernel
- Various fixes and improvements

New version crashes when trying to remove a kernel.
New version also cannot install recent mainline kernel because of missing checksum files:
So for me that means zero usability after this update (as a user who paid for this app).

The mainline kernels are provided by Ubuntu. You do know that right?
The 5.16 packages on the mainline PPA server are not built correctly.

There seems to be multiple packages for the same kernel with different signatures.
Hi Tony,
Just bought your kernel tool and seeing the same error. looks like there are 2 versions of the kernel packages but your tool isn’t seeing the correct checksum in the checksum file, any chance of a fix?
There shouldn’t be 2 versions of the same package on the server.
These kind of build issues come up often.
I’ll wait for the next kernel release (5.16.1) before making any changes in the app..Added a workaround in Ukuu v21.01.1.
Hi Dave!
Can you try to remove a kernel and check if ukuu is asking for the password for root rights when trying? Or if it just crashes, like on my machine? Thank you!
Hi Rev, needed to input password to enable the sudo commands
After update seems to be working as expected, uname -r shows 5.16 and new bluetooth dongle working. Thanks Tony
The latest version is crashing when I try to remove a kernel too.
Added a fix in v22.01.2. Send an email to [email protected] with more details if it is still not resolved
The fix in v22.01.2 did remove the problem, Ukuu not asking for the root password when trying to remove a kernel. And therefore I can remove Kernels within the GUI again. Thank you for fixing the issue!
By the way: It looks like the header files remain on the system, when removing a kernel. Can you fix that?
Please send me an email with a screenshot of the problem along with the log file. Use the ‘Save Log’ button in the progress window to save the log.

Please let know if the update for ubuntu/Pop Impish version and the future releases are planned. It been a while since the last update.
The repo installed on your system is not correct. It should have “focal” in the URL. Which distribution are you using? Re-run the installation command to fix this issue.
