Bash script for Ubuntu (and derivatives as LinuxMint) to easily (un)install kernels from the Ubuntu Kernel PPA.
🔓 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.
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: 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!)
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
Install latest version:
~ $ sudo ubuntu-mainline-kernel.sh -i

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