* Better version sorting

Have remote list sorted correctly by default for better readability latest version selection (in case `-rc*` versions are used).

* Further simplify version sorting

Take advantage of Debian's convention of using ~ for pre-release suffixes.

ubuntu-mainline-kernel.sh

Bash script for Ubuntu (and derivatives as LinuxMint) to easily (un)install kernels from the Ubuntu Kernel PPA.

Warnings

⚠️ Use this script at your own risk. Be aware that the kernels installed by this script are unsupported

🔓 Do not use this script if you don't have to or don't know what you are doing. You won't be covered by any security guarantees. The intended purpose by Ubuntu for the mainline ppa kernels is for debugging issues.

ℹ️ We strongly advise to keep the default Ubuntu kernel installed as there is no safeguard that at least one kernel is installed on your system.

Install

apt install wget
wget https://raw.githubusercontent.com/pimlie/ubuntu-mainline-kernel.sh/master/ubuntu-mainline-kernel.sh
chmod +x ubuntu-mainline-kernel.sh
sudo mv ubuntu-mainline-kernel.sh /usr/local/bin/

If you want to automatically check for a new kernel version when you login:

wget https://raw.githubusercontent.com/pimlie/ubuntu-mainline-kernel.sh/master/UbuntuMainlineKernel.desktop
mv UbuntuMainlineKernel.desktop ~/.config/autostart/

Usage

Usage: ubuntu-mainline-kernel.sh -c|-l|-r|-u

Download & install the latest kernel available from kernel.ubuntu.com

Arguments:
  -c               Check if a newer kernel version is available
  -i [VERSION]     Install kernel VERSION, see -l for list. You don't have to prefix
                   with v. E.g. -i 4.9 is the same as -i v4.9. If version is
                   omitted the latest available version will be installed
  -l [SEARCH]      List locally installedkernel versions. If an argument to this
                   option is supplied it will search for that
  -r [SEARCH]      List available kernel versions. If an argument to this option
                   is supplied it will search for that
  -u [VERSION]     Uninstall the specified kernel version. If version is omitted,
                   a list of max 10 installed kernel versions is displayed
  -h               Show this message

Optional:
  -p, --path DIR       The working directory, .deb files will be downloaded into
                       this folder. If omitted, the folder /tmp/ubuntu-mainline-kernel.sh/
                       is used. Path is relative from $PWD
  -ll, --low-latency   Use the low-latency version of the kernel, only for amd64 & i386
  -lpae, --lpae        Use the Large Physical Address Extension kernel, only for armhf
  --snapdragon         Use the Snapdragon kernel, only for arm64
  -do, --download-only Only download the deb files, do not install them
  -ns, --no-signature  Do not check the gpg signature of the checksums file
  -nc, --no-checksum   Do not check the sha checksums of the .deb files
  -d, --debug          Show debug information, all internal commands echo their output
  --rc                 Also include release candidates
  --yes                Assume yes on all questions (use with caution!)

Elevated privileges

This script needs elevated privileges when installing or uninstalling kernels.

Either run this script with sudo or configure the path to sudo within the script to sudo automatically

Dependencies

  • bash
  • gnucoreutils
  • dpkg
  • wget (since 2018-12-14 as kernel ppa is now https only)

Optional dependencies

  • libnotify-bin (to show notify bubble when new version is found)
  • bsdmainutils (format output of -l, -r with column)
  • gpg (to check the signature of the checksum file)
  • sha1sum/sha256sum (to check the .deb checksums)
  • sudo

TODO

  • Support daily kernel builds (on hold until there is significant demand for this, PRs are also welcome)
