Ubuntu Kernel Update Utility (Ukuu) moved to the paid license model with the latest version

Ukuu or Ubuntu Kernel Update Utility is a very popular unofficial GUI tool for easily installing the latest mainline Linux kernel on Ubuntu-based distributions. Moving To the latest 19.01 version of the paid ($ 11) licensing model.
Ukuu displays a list of available kernels on the Ubuntu Mainline kernel website, allowing users to easily download and install the required version. The utility can also delete installed kernels, display changes in the selected Linux version, display notifications when new kernels are available, and so on.

Ukuu v18.9, the last free open source version of the Ubuntu kernel update utility

With the release of Ukuu’s 19.01 version, the application requires a personal license for $ 11, and the source code is no longer available. Application developer Tony George, notes The reason for this is the lack of donations, while other options are to stop development or require a paid license:

The latest version (v18.9) of this application has 60,000 downloads, but in the past two years, only 12 users have donated. I can’t continue to use this app for free, and making it seem to be a better option than stopping the project.

He said in the comments:

Open application outsourcing when you are the only developer will only increase your workload (as more and more people request changes), and will not benefit you in any way. If you have the time and energy, the FOSS project may be interesting at first, but as the number of users increases and requests continue to accumulate, it may become a problem.

Tony George maintains multiple projects and he attempts to monetize in various ways. He provided some for free (such as Groot or TimeShift) (using a donation model), while others included paid additional content such as Polo (file manager) or Aptik (used to migrate settings and data from one Linux installation to another Linux installation tool). There is also Umix, a paid Linux distribution based on Ubuntu 18.04 and Unity 7 desktop.
