ubuntu apt-get update失败

1.出现错误：E:Could not get lock /var/lib/apt/lists/lock - open (11: Resource temporarily unavailable)

出现这个问题的原因可能是有另外一个程序正在运行，导致资源被锁不可用。而导致资源被锁的原因，可能是上次安装时没正常完成，而导致出现此状况。
 
解决方法：把 /var/lib/apt/lists 中的文件全部删掉

输入以下命令
sudo rm /var/cache/apt/archives/lock
 
sudo rm /var/lib/dpkg/lock
 
之后再安装想装的包，即可解决

2.出现错误：E: Some index files failed to download. They have been ignored, or old ones used instead.
解决方法：
To upgrade a really old Ubuntu release, we first need to edit our sources.
list and change all(xx.)archive.ubuntu.com to old-releases.ubuntu.com.
 
   $ sudo emacs /etc/apt/sources.list

So your lines should instead of

   deb http://archive.ubuntu.com/ubuntu jaunty main restricted universe

look like

   deb http://old-releases.ubuntu.com/ubuntu jaunty main restricted universe

In this example I use jaunty release. But it works the same on other releases.
Now update the repos  

   $ sudo apt-get update
