我删除了许多 3.13.0-x 版本的 linux-images，只留下了一些安装的版本。

如您所见，只有 3.13.0-x 版本。
但我也很多linux-headers 为 3。16.0-x 和 3.19.0-x 版本。

为什么？
由于我没有 3.16 和 3.19 内核，为什么我的系统会下载并安装所有这些 3.16 和 3.19 标头？
答案1
首先，删除 Utopic 和 Vivid 的元包：
sudo apt-get purge linux-headers-generic-lts-utopic linux-headers-generic-lts-vivid
...然后 autoremove 命令应该起作用：
sudo apt-get --purge autoremove
您可能还想尝试删除所有标题和内核，但最新的是：
试运行，打印出要删除的包
dpkg -l linux-* | awk '/^ii/{ print $2}' | grep -v -e `uname -r | cut -f1,2 -d"-"` | grep -e [0-9] | grep -E "(image|headers|modules)" | xargs sudo apt-get --dry-run remove将删除除最新内核、头文件和模块之外的所有文件
dpkg -l linux-* | awk '/^ii/{ print $2}' | grep -v -e `uname -r | cut -f1,2 -d"-"` | grep -e [0-9] | grep -E "(image|headers|modules)" | xargs sudo apt-get -y purge
