ubuntu-mainline-kernel.sh
Bash script for Ubuntu (and derivatives as LinuxMint) to easily (un)install kernels from the Ubuntu Kernel PPA.
Install
apt install wget
wget https://raw.githubusercontent.com/pimlie/ubuntu-mainline-kernel.sh/master/ubuntu-mainline-kernel.sh
or
wget https://gitee.com/cnmirror/ubuntu-mainline-kernel.sh/raw/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/
Warning ⚠️
Use this script at your own risk. You could remove all kernels with this script and leave your system unbootable.
There is no safeguard that at least one kernel is installed on your system. Be especially careful with the --yes option.

--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 command's echo their output
--rc Also include release candidates
--yes Assume yes on all questions (use with caution!)
