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.
The Ubuntu mainline kernels come with GPG-signed hashes (CHECKSUMS, CHECKSUMS.gpg), but this utility ignores them. Since the downloads are over plain HTTP, there is nothing to stop a network attacker from modifying the kernel packages in transit.
