ubuntu-mainline-kernel.sh：Ubuntu（及其衍生产品）的Bash脚本，可从Ubuntu Kernel ...

ubuntu-mainline-kernel.sh ================= Bash script for Ubuntu (and derivatives as LinuxMint) to easily (un)install kernels from the [Ubuntu Kernel PPA](http://kernel.ubuntu.com/~kernel-ppa/mainline/). Warnings ----------------- :warning: Use this script at your own risk. Be aware that the kernels installed by this script are [unsupported](https://wiki.ubuntu.com/Kernel/MainlineBuilds#Support_.28BEWARE:_there_is_none.29) :unlock: Do not use this script if you don't have to or don't know what you are doing. You won't be [covered](https://github.com/pimlie/ubuntu-mainline-kernel.sh/issues/32) by any security guarantees. The intended purpose by Ubuntu for the mainline ppa kernels is for debugging issues. :information_source: 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 Example output ------------------- Install latest version: ``` ~ $ sudo ubuntu-mainline-kernel.sh -i Finding latest version available on kernel.ubuntu.com Latest version is v4.9.0 but seems its already installed, continue? (y/N) Will download 5 files from kernel.ubuntu.com: CHECKSUMS CHECKSUMS.gpg linux-headers-4.9.0-040900-generic_4.9.0-040900.201612111631_amd64.deb linux-headers-4.9.0-040900_4.9.0-040900.201612111631_all.deb linux-image-4.9.0-040900-generic_4.9.0-040900.201612111631_amd64.deb Signature of checksum file has been successfully verified Checksums of deb files have been successfully verified with sha256sum Installing 3 packages [sudo] password for pimlie: Cleaning up work folder ``` Uninstall a version from a list ``` ~ $ sudo ubuntu-mainline-kernel.sh -u Which kernel version do you wish to uninstall?
