When ever i try to install or upgrade a package with apt-get
it downloads the package but instead of installing the pckg
it fills the terminal window with a msg about the package--
sercurity level=low--- and a bunch of other stuff it never
installs anything.

using: apt-get install 'pkg_name' or apt-get upgrade 'pkg_name'
I've done apt-get clean and atuoclean, but i just can't seem
to get apt-get to install anything.

How do i overide this?
I've read the apt-get man but didn't see any thing about this
problem i'm having


Please advise.

Hmmm! Might help if you told us what version of Debian you're running ... Stable, Testing, Unstable. Depending on your answer to that, it might also help to see your /etc/apt/sources.list file, and maybe an apt.conf file if you have one

Here is my soucrces.list:

# /etc/apt/sources.list for Knoppix
# If you want to do a "full upgrade", you should first
# upgrade the Packages from Debian/unstable (KDE & Co.)
# before doing a (dist-)upgrade for Debian/testing.
#
# See sources.list(5) for more information, especialy
# Remember that you can only use http, ftp or file URIs
# CDROMs are managed through the apt-cdrom tool.

Why did you put your question in a Debian forum when you're using Knoppix? Knoppix is a Debian derivative like 100+ other distros. It ain't Debian.

You may be able to make it compatible with Debian by changing your sources.list file to look something like this:
Then ... # apt-get update && apt-get dist-upgrade

Of course there's no guarantee. If you want Debian, it's best to start with Debian.
