大伟哥的工作电脑使用Ubuntu 16.04系统，已经很久没有更新了，今天正好有空，就运行了sudo apt update, sudo apt upgrade让它在后台自已更新去了。
因为要更新的软件比较多，需要花费挺长时间，大伟哥也没怎么在意，只是在运行结束后看了一下报错，上面显示因为boot分区空间不够，升级linux内核的时候出错了：
在处理时有错误发生：
linux-image-extra-4.4.0-97-generic
linux-image-generic
linux-generic
E: Sub-process /usr/bin/dpkg returned an error code (1)
之前也发生了同样的问题，系统提示可以运行sudo apt-get autoremove清除不需要的依赖的，而多次升级后/boot分区里已经有了多个之前版本的Linux内核，因此大伟哥决定先运行一下这个命令，看能不能自动给/boot分区清理出一部分空间来，这样也省得我再查文档手动清除旧的内核文件了。实验证明这个命令真的有效果，/boot分区清理出了100多M的空间，应该也够安装新的内核了。
再次执行sudo apt update/sudo apt upgrade, 系统并没有接着安装上次没有完成安装的内核，而是报错如下：

试一下sudo apt install命令看看不能能安装：

这样最新的内核版本4.4.0.130.136就安装好了。其实我觉得这样用autoremove腾出分区空间还是有点风险的,有可能会误删掉其他有用的软件。
