困扰许久的问题，apt 效验和不符

bsdwiki

系统：debian testing

无论是用apt-get 还是用 aptitude 来下载软件，都会出现效验和不符的提示，换了新的公钥，把源从大陆换到台湾日本又换到欧洲，都是如此，请前辈们指点一下吧，好长时间了

以前貌似遇到过，不过很久没用忘记了。lz把错误提示贴出来。

B3. How do I use Apt ?
Apt originally was developed by the Debian project to work together with DEB packages. Since there are not many functional differences between RPM and DEB packages, Conectiva ported Apt to use RPM.

To install Apt, download the latest package for your distribution from: http://dag.wieers.com/packages/apt/. The configuration of Apt is inside the rpmforge-release package.

If you've done that, the rest is simple. Update the local repository meta-data by doing:

apt-get update
You can upgrade your system with the latest packages with:

apt-get upgrade
And finally you can add new software by typing:

apt-get install <name of package>
Or search for software in the local repository meta-data:

apt-cache search <keyword> apt-cache show <name of package>
From time to time you may want to save some diskspace:

apt-get clean
Remember to update your local repository often before upgrading or installing software, so that you can enjoy the latest and greatest.

Some people rather use a graphical program to select and install packages. Apt has a nifty graphical front-end, called Synaptic. You can install it by doing:

apt-get install synaptic
Or download it from: http://dag.wieers.com/packages/synaptic/

截图如下，换过很多源了，也更换了公钥了，就是下载某些软件的时候会出现效验和不符，请老大们帮帮忙
