System Requirements

Supported Operating Systems

  • This app is meant for use on Ubuntu-based Linux distributions as it installs kernels that are built with Ubuntu-specific patches. This includes distributions like Xubuntu, Linux Mint, Elementary OS, Pop OS, etc.
  • Debian and Debian-based distributions are not supported.
  • All Ubuntu releases from 16.04 LTS (Xenial) and later are supported. This includes distributions based on Ubuntu 16.04 such as Linux Mint 18+. Older releases of Ubuntu and their derivatives are not supported.

Supported Hardware

  • 64-bit packages (amd64) are available for Intel and AMD systems (x86).
  • 32-bit systems are not supported. Ubuntu has stopped providing 32-bit builds of mainline kernels since Linux v5.3.
  • It is not available for ARM (Raspberry Pi, etc).

  • An APT repository is available for installation and updates

Known Issues & Limitations

  • Kernels that are downloaded and installed by this app are provided by Canonical in their mainline kernel repository. This app acts as a front-end for downloading, installing and managing mainline kernels.
  • Ubuntu’s Live patch service is only for official kernels and does not work with mainline kernels.
  • This app cannot be used in containerised and virtual systems where the kernel is shared by multiple instances. If your system is hosted on the cloud, or on a shared server, then it is most likely a virtual system.
  • Administrator privileges are required to run the app and install, update or remove kernels.
  • Mainline kernels are unsigned and cannot be used along with secure-boot unless you sign it with your own key. The steps involved are complicated and will not be easy for most users. It is recommended to keep secure boot disabled if you wish to use mainline kernels.
  • Mainline kernels do not support ZFS due to legal issues. Use the official Ubuntu kernels if you need proper ZFS support.
