I'm booting Hardy Heron from a persistent USB (http://www.pendrivelinux.com/2008/05...-from-live-cd/) and I'm trying to install EnvyNG and Wine. I've tried

sudo apt-get install envyng-gtk

but I keep getting

ubuntu@ubuntu:~$ sudo apt-get install envyng-gtk
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Couldn't find package envyng-gtk

As for Wine, it doesn't show up in my "Add/Remove..." list.

Am I getting these errors because something is wrong with my install? Or are the packages messed up because this is technically a live USB and not a true install? I'd appreciate any input at all. Thank you for you time.
