I am using a HDD installed version of Knoppix.
When I use apt-get, the following wants to be pulled from testing
But when it downloads and installation starts, I get errors (cannot read ELF header, etc.) and apt always exits -- anyone might try it, and probably will get the same. The package size is only 18 K.

At first, I thought that the above Debian package is corrupted on the mirror it is downloaded from. So I got it from the net via FTP and tried
dpkg --install on it, but got the same errors.

How do you guys install this cloop thing successfully?
