Ubuntu 中有许多实用程序可以将 Linux 内核升级到最新的稳定版本。我们之前已经写过关于这些实用程序的文章，例如 Linux Kernel Utilities (LKU)、Ubuntu Kernel Upgrade Utility (UKUU) 和 Ubunsys。
另外还有一些其它实用程序可供使用。我们计划在其它文章中包含这些，例如 ubuntu-mainline-kernel.sh 和从主线内核手动安装的方式。
今天我们还会教你类似的使用工具 —— UKTools。你可以尝试使用这些实用程序中的任何一个来将 Linux 内核升级至最新版本。
最新的内核版本附带了安全漏洞修复和一些改进，因此，最好保持最新的内核版本以获得可靠、安全和更好的硬件性能。
有时候最新的内核版本可能会有一些漏洞，并且会导致系统崩溃，这是你的风险。我建议你不要在生产环境中安装它。
建议阅读：
- Linux 内核实用程序（LKU）- 在 Ubuntu/LinuxMint 中编译，安装和更新最新内核的一组 Shell 脚本 [1]
- Ukuu – 在基于 Ubuntu 的系统中安装或升级 Linux 内核的简便方法 [2]
- 6 种检查系统上正在运行的 Linux 内核版本的方法 [3]
什么是 UKTools
UKTools[4] 意思是 Ubuntu 内核工具，它包含两个 shell 脚本 ukupgrade 和 ukpurge。
ukupgrade 意思是“Ubuntu Kernel Upgrade”，它允许用户将 Linux 内核升级到 Ubuntu/Mint 的最新稳定版本以及基于 kernel.ubuntu.com[5] 的衍生版本。
ukpurge 意思是“Ubuntu Kernel Purge”，它允许用户在机器中删除旧的 Linux 内核镜像或头文件，用于 Ubuntu/Mint 和其衍生版本。它将只保留三个内核版本。
此实用程序没有 GUI，但它看起来非常简单直接，因此，新手可以在没有任何问题的情况下进行升级。
我正在运行 Ubuntu 17.10，目前的内核版本如下：
| $ uname -a | |
| Linux ubuntu 4.13.0-39-generic #44-Ubuntu SMP Thu Apr 5 14:25:01 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux |
运行以下命令来获取系统上已安装内核的列表（Ubuntu 及其衍生产品）。目前我持有 7 个内核。
| $ dpkg --list | grep linux-image | |

如何安装 UKTools
在 Ubuntu 及其衍生产品上，只需运行以下命令来安装 UKTools 即可。
在你的系统上运行以下命令来克隆 UKTools 仓库：
$ git clone https://github.com/usbkey9/uktools
进入 uktools 目录：
$ cd uktools
运行 Makefile 以生成必要的文件。此外，这将自动安装最新的可用内核。只需重新启动系统即可使用最新的内核。

使用以下命令重新检查已安装内核的列表。它将只保留三个旧的内核。
| $ dpkg --list | grep linux-image | |
| ii linux-image-4.13.0-38-generic 4.13.0-38.43 amd64 Linux kernel image for version 4.13.0 on 64 bit x86 SMP | |
| ii linux-image-4.13.0-39-generic 4.13.0-39.44 amd64 Linux kernel image for version 4.13.0 on 64 bit x86 SMP | |
| ii linux-image-extra-4.13.0-38-generic 4.13.0-38.43 amd64 Linux kernel extra modules for version 4.13.0 on 64 bit x86 SMP | |
| ii linux-image-extra-4.13.0-39-generic 4.13.0-39.44 amd64 Linux kernel extra modules for version 4.13.0 on 64 bit x86 SMP | |
| ii linux-image-generic 4.13.0.39.42 amd64 Generic Linux kernel image | |

下次你可以调用 do-kernel-upgrade 实用程序来安装新的内核。如果有任何新内核可用，那么它将安装。如果没有，它将报告当前没有可用的内核更新。
| $ do-kernel-upgrade | |
| Kernel up to date. Finishing |
再次运行 do-kernel-purge 命令以确认。如果发现超过三个内核，那么它将移除。如果不是，它将报告没有删除消息。
| $ do-kernel-purge | |
| Ubuntu Kernel Purge - by Caio Oliveira | |
| This script will only keep three versions: the first and the last two, others will be purge | |
| ---Current version: | |
| Linux Kernel 4.16.7-041607 Generic (linux-image-4.16.7-041607-generic) | |
| Nothing to remove! | |
| Thanks for using this script!!! |
