我的/boot分区快满了，每次重新启动系统时都会收到警告。我已经删除了旧的内核包（linux-headers ...），实际上我这样做是为了安装自动更新附带的较新内核版本。
安装新版本后，分区又快满了。那我还能删除什么？是否有其他一些与旧内核映像相关的文件？
这是我的/boot分区上的文件列表：

目前，我正在使用3.0.0-14-generic内核。
首先，我相信我应该说我本周早些时候刚刚安装了 Ubuntu 18.04 LTS，所以我基本上什么都不知道。
我今天在空闲安装python3时遇到错误：
dpkg: error processing package linux-modules-4.15.0-22-generic (--configure):
