This is probably a type of "is it plugged in?" question, but after getting a default Rackspace image of Ubuntu 11.04 up. Running command (as root)
apt-get install rake
Fails with error

E: Unable to locate package rake
I'm missing something simple I'm sure.
It appears that rake package is not in the 11.04 sources, but it is in 10.10 sources.
To get apt-get install rake to work on 11.04:
Add the following lines to /etc/apt/sources.list
deb http://archive.ubuntu.com/ubuntu/ maverick main restricted universe
deb-src http://archive.ubuntu.com/ubuntu/ maverick main restricted universe
Update package listing
apt-get update
Now rake should be available:
apt-get install rake
Try gem install rake
It may be better to use rvm than Ubuntu's Ruby and Gem.
