I am running off the CD. I try apt-get install mit-scheme under user knoppix and get

W: Not using locking for read only lock file /var/lib/dpkg/lock
E: Unable to write to /var/cache/apt/
E: The package lists or status file could not be parsed or opened.

I switch to root and get the same response. After remounting /KNOPPIX to rw I get

Reading Package Lists... Done
Building Dependency Tree... Done
E: Couldn't find package mit-scheme

It says it can't find the package but on debian.org's site they call the package mit-scheme. The link is

http://packages.debian.org/unstable/...it-scheme.html

Any help would be appreciated. Thanks.
