I installed the Nov 3 Knoppix, then did a hd install, and all was well.

But, I started adding packages with apt-get and managed to screw things up.

Everything on my system is now the 'unstable' version and it IS unstable!
Or at least, many things crash, and most importantly, I have no sound..
(it WAS working great at first)

So my question is: what's the simplest way to get back to an earlier state?
I've poked around the debian sites, and most people say
"there is no easy way to downgrade". One suggested a preferences
file with a priority of 1001, but that still did nothing!

Would it be wise to reinstall from knoppix? will it install over
a "newer" debian?

The system itself seems to be confused about what version
it's actually using. My apt.conf says "testing", yet everything is unstable
(except php4 which is stable !?!),
However, when I try to build from source, the
dependencies indicate that I'll be getting a woody version!
And then build-deps says " broken deps, do a -f install",
but that finds nothing to do.

Do I sound confused? well, I am!

I have separate partitions for /, /usr, and others..
Shall I just wipe them and boot from the cd to start all over again?

thanks,
