1 For get a Fast Speed , I choose 163 as my apt-get mirror site.
u can edit /etc/source.list, and replace it's content with following codes:
deb http://mirrors.163.com/ubuntu/ jaunty main restricted universe multiversedeb http://mirrors.163.com/ubuntu/ jaunty-security main restricted universe multiversedeb http://mirrors.163.com/ubuntu/ jaunty-updates main restricted universe multiversedeb http://mirrors.163.com/ubuntu/ jaunty-proposed main restricted universe multiversedeb http://mirrors.163.com/ubuntu/ jaunty-backports main restricted universe multiversedeb-src http://mirrors.163.com/ubuntu/ jaunty main restricted universe multiversedeb-src http://mirrors.163.com/ubuntu/ jaunty-security main restricted universe multiversedeb-src http://mirrors.163.com/ubuntu/ jaunty-updates main restricted universe multiversedeb-src http://mirrors.163.com/ubuntu/ jaunty-proposed main restricted universe multiversedeb-src http://mirrors.163.com/ubuntu/ jaunty-backports main restricted universe multiverse
then type following command:(so that ubuntu can update source repos)
sudo apt-get update
When this update is closing to the end , I caught an error( didn't encounter this error on my work station PC),when on my laptop:
获取：4 http://mirrors.163.com jaunty/universe Packages [4757kB] 下载 6366kB，耗时 1min 41s (62.6kB/s) 正在读取软件包列表... 完成W: GPG error: http://mirrors.163.com jaunty-updates Release: 下列签名无效： BADSIG 40976EAF437D05B5 Ubuntu Archive Automatic Signing Key <ftpmaster@ubuntu.com>W: 您可能需要运行 apt-get update 来解决这些问题
So I baidu this message ,then I searched this [url=http://cache.baidu.com/c?m=9f65cb4a8c8507ed4fece76310428a265e0b97634b9080522392d45f931306011271e3cc767e0d40889239215ced120dfdf041306d4137b6ef8e9f4babb8912b2f8833712d5cd04e42804fee901332c1519658e2aa1df0bb8065c0fad4d2da0251cd03127bf0f7&p=9e6d8e16d9c713ff57eb93364d5f&user=baidu]page[/url], which said:

So I ignored this error message(But still want to know why)
