root@latop:/usr/share# uname -a #当前使用的内核
Linux latop 4.19.0-kali1-amd64 #1 SMP Debian 4.19.13-1kali1 (2019-01-03) x86_64 GNU/Linux


有image的就是内核文件
删除老的内核文件，如：

#me
root@latop:~# apt-get remove   linux-image-4.6.0-kali1-amd64 


deinstall 就是没安装的 所以不用remove



或者，可以手工清理/var/cache/apt/archives目录里的文件



</pre>

=清理apt缓存以及无用包=
<pre>
sudo apt-get clean
sudo apt-get autoclean
sudo apt-get autoremove
</pre>
