我遇到了空间不足的/boot问题，并发出了以下命令来尝试清除它：
# rm /boot/vmlinuz-4.4.0-{x, y, z, 70}-generic && dpkg --purge linux-image-4.4.0-{x, y, z, 70}-generic
其中x，y是z我删除的版本，我不记得它们的编号了。
但是当我尝试更新任何内容时，控制台上会显示以下内容：
# apt-get update && apt-get upgrade

答案1
正如您所发现的，在清除软件包之前删除文件会给软件包管理器带来问题。您基本上只需要恢复软件包管理器抱怨的已删除内容。恢复的文件可能为零长度，软件包管理器并不关心，因此请使用“touch”命令。例如：
sudo touch /boot/vmlinuz-4.4.0-70-generic
您可能还需要创建一些目录，但是当包管理器找到它想要的文件时，它就会成功完成。
