当我尝试：
sudo apt dist-upgrade
我收到以下错误：
vagrant@ubuntu-16:~$ sudo apt dist-upgrade Reading package lists... Done Building dependency tree Reading state information... Done Calculating upgrade...

对不起，以恢复旧的问题，但我偶然发现，试图解决这个问题，没有find明确的答案。
下面修复它在我的构build：
rm -rf /etc/udev/rules.d/70-persistent-net.rules touch /etc/udev/rules.d/70-persistent-net.rules
这将删除该文件夹，并创build一个文件，而不是像initramfs所期望的那样
删除之前，您可能需要检查文件夹是否为空。
