How do I definitely install Pharo on Ubuntu 15.04?

Have you tested the instructions for Gnu/Linux (including Ubuntu) here:

http://pharo.org/gnu-linux-installation

They are for 14.04, but they should work and if not, a more focused question after you test what's working and what's not could help us to help you better.

Cheers,
