We use(d, actually) knoppix 3.8.1, all worked fine and we were happy.

Today we decided "to upgrade" our system. I verified by "apt-get upgrade -s" that we receive only "stable" and "testing" packages.

Run...

After computer restart, we've got surprises:
1) KDE is not running (asks for password, starts to log-in, then black screen, then KDE again asks for password,... )
2) NIS server YP binding takes ~10 min during each start-up. It is not responding to Ctrl-Z, Ctrl-Q, Esc, whatever.

Currently I'm saving my files for reinstall the Knoppix from scratch (using Windows

Any help is appreciated

PS I'm completely newbie to Linux, seems (well, only 6 month of user experience)

PS It is so very very sad, that apt-get doesn't work for "simple" user

This is knoppix, not a "pure debian" . Apt do work for simple users using stable or testing. I don't really like apt pinning or mixing sources unless i really have to.

If you want something considered by lots of people stable, use debian stable(sarge) or change all references to unstable to stable or testing in your /etc/apt/sources.list.

You can run a pretty safe mixed distros flavour in Debian by using
apt-listbugs. It warns you of the bugs with several 'severity' degrees.
Then it's up to you to decide to upgrade or not. I did try to upgrade
Mozilla to the latest version, was warned not to, did anyway : result,
video flickering all the time. Exit Mozilla.
But at least you don't wake up after upgrading to discover your Gnome
or KDE all messed up.
And I heartily agree with mrcheeks. Knoppix is NOT Debian, Mepis and
Ubuntu either. Closest I found seems to be Libranet (not free of charge
for latest version).

Please do not post the same thread in more than one forum. Picking the most relevant forum and posting it once there makes it easier for other members to help you and keeps the discussion all in one place.
