Talk:Knowing Knoppix/Other applications

Confusion at end of article. I am not qualified to fix.
At the very end of this article is this... - "Note to all debian users. Anyone who has used debian before will probably be itching to issue

apt-get upgrade

You are urged not to do this as knoppix has many custom scripts that apt-get upgrade seems to break." - But a few lines previous it recommends doing...

"sudo apt-get update"

by using the sudo, is this OK? It seems to me (a novice) that sudo makes it worse, giving more power. I hope some knowledgeable person can clear this up as it looks like a serious problem for beginners like me.

Edit; I see the problem, update and upgrade are not the same. Disregard a beginner :-)
