Good news :
I was able to install it from deb pack (although there are some problems) but NessusClient needed libqt4 to run, I found it in gslapt but it's too large.
I tried to use OpenVAS client with Nessus (I did that with Ubuntu before) but I was unsuccessful, anyway, I thought I will try OpenVAS itself.
I found that it actually uses Nessus plugins, I downloaded it, and now I'm updating it with the latest Nessus plugins using the script that came with it "openvas-nvt-sync"
so far that's what I could do, I think the problem is now solved.
Thanks all for ur replies.
