sorry if there had been the same post.

I've flash drive Toshiba 8Gb with Knoppix 7.2 live CD and I set 5Gb to persistant file.

Why do I always fail when install new applications?
What the live cd can not install new applications? while the command "apt -get update" can be done.

is there a list of repository for knoppix?

Thanks and sorry for my bad english.
