Can I install Unity on 10.04?
I am completely new to Ubuntu and I have no idea how to install it correctly. The command
sudo apt-get install unity doesn't work, and I don't know how to fix it...
Unity is not available for Ubuntu 10.04, you have to use at least Ubuntu 11.04 (where it is installed by default).
As support for 11.04 ends 2012-10-31 and Unity isn't that stable there anyway better use 12.04 for Unity.
