在 Ubuntu 14.10 上，Udev 拒绝更新。
我执行了这段代码：
sudo apt-get upgrade
输出结果如下：
Reading package lists... Done
Building dependency tree
Reading state information... Done
You might want to run ‘apt-get -f install’ to correct these.
The following packages have unmet dependencies.
udev : Depends: libudev1 (= 208-8ubuntu8.1) but 208-8ubuntu8.2 is installed
E: Unmet dependencies. Try using -f.
于是我做了：
sudo apt-get -f install
输出：
