Q:

How can I install the Equinox theme?

I'm following the instructions on this page:
sudo add-apt-repository ppa:tiheum/equinox
sudo apt-get update
sudo apt-get install gtk2-engines-equinox equinox-theme

But I'm getting:
E: Unable to locate package equinox-theme

A:

Equinox is not available for 11.10, and it will only show up in the PPA for 11.04 and below.
The reason it is not available is because the entire equinox engine would need to be ported to GTK+ 3.x, which is not a trivial matter. It will probably be a while if it ever happens at all.
