这篇帖子的更新软件源做法做了，选择完新的服务器之后，点击CLOSE
但他却提示
这是怎么回事啊The information about available software is out-of-date
To install software and updates from newly added or changed sources, you have to reload the information about available software.
You need a working internet connection to continue.
然后我选择任何一个软件源（包括原来的Server For 中国）他都这么提示，我的网络是连接好的，可以用Firefox上网
而且我在没法再使用language support了，一更新就提示
另外我必须要换软件源，因为我需要更新语言，但原来的软件源更新速度，只有几千B/S，太慢了Could not download all repository indexes
The repository may no longer be available or could not be contacted because of network problems. If available an older version of the failed index will be used. Otherwise the repository will be ignored. Check your network connection and ensure the repository address in the preferences is correct.
