按照指导，老老实实先安装mercurial，手贱敲了个ctrl+c（天哪我什么时候才能改掉在terminal里敲ctrl+c的毛病啊我已经快要给自己跪了），然后又手贱敲了个ctrl+z，然后mercurial的安装进程就中止了。

再重新安装，就出现错误：

E: Could not get lock /var/lib/dpkg/lock - open (11 Resource temporarily unavailable)
E: Unable to lock the administration directory (/var/lib/dpkg/) is another process using it? 
上网查找，解决方式是杀掉进程：

sudo rm /var/lib/apt/lists/lock

然后又好了。但是再重新安装，好像就不知所云了。
cathysia@mancinism:~$ sudo apt-get install mercurial
E: dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to correct the problem.
