Hello, I've been trying to install preenv on my nokia n900 since Im bored playing the same old basic games. But, I have never been through the Xterminal before, I dont know much bout these, I've tried following instructions posted in many threads, but none have helped me until now. I installed the rootsh as asked, and activated the repositories as well (even if I dont really know what it actually means) but when I enter apt-get preenv it plainly says, E: package not found (something like that)

I read in a post that, repositories are not avalaible in all countries? How do I know it is available in my country?

Plz help me out
