因为工具的需求，因此需要在Ubuntu 16.04下安装指定版本的内核，因此需要将新版本的内核删除掉，然后重新安装，这里记录下操作过程
查看当前使用的内核版本:
root@ubuntu:~# uname -aLinux ubuntu 4.4.0-142-generic #168-Ubuntu SMP Wed Jan 16 21:00:45 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux
安装需要使用的对应版本的Ubuntu linux内核:
root@ubuntu:~# apt-get install linux-image-4.4.0-97-generic
然后查看系统中已经安装的所有内核
root@ubuntu:~# dpkg --get-selections |grep linux-imagelinux-image-4.4.0-142-generic installlinux-image-4.4.0-62-generic installlinux-image-extra-4.4.0-142-generic installlinux-image-extra-4.4.0-62-generic installlinux-image-generic install
卸载不需要的内核。
root@ubuntu:~# apt-get remove linux-image-4.4.0-62-genericroot@ubuntu:~# apt-get remove linux-image-4.4.0-142-generic
需要注意的是，这里的linux-image-4.4.0-142-generic是当前正在使用的内核，卸载之后Ubuntu16.04会提示用户升级升级grub

因此我们需要更新下grub
root@ubuntu:~# update-grubGenerating grub configuration file ...Found linux image: /boot/vmlinuz-4.4.0-97-genericFound initrd image: /boot/initrd.img-4.4.0-97-genericdone
搞定之后重启系统，然后确定系统使用了我们制定版本的内核
root@ubuntu:~# rebootroot@ubuntu:~# uname -aLinux ubuntu 4.4.0-97-generic #120-Ubuntu SMP Tue Sep 19 17:28:18 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux
下一步，我们锁定当前内核版本使之在apt dist-upgrade时也不会被升级
root@ubuntu:~# apt-mark hold linux-image-4.4.0-97-genericlinux-image-4.4.0-97-generic set on hold.
测试下，果然不会被升级了。至此，可以安心的去安装软件了
