A paid version of Ukuu is now available with more features. https://teejeetech.in/2019/01/20/ukuu-v19-01/ Kernel Update Utility for Ubuntu-based distributions. Provides desktop notifications when new mainline kernel is available. Lists kernels from http://kernel.ubuntu.com/~kernel-ppa/mainline/ with options to install and remove.
Fresh Swedish update! I also added missing strings for /Gtk/MainWindow.vala - Line: 425, 426
