Before installing/upgrading, there are some important known issues,
especially if:
* AMD GPU/IGP
* Dell XPS 13
* EFI
* Virtualbox
* Apple Hardware

are involved. Other issues are listed too.

This Sunday, we'll have the most popular Ubuntu ISOs for 15.04 at the
weekly meetup. Bring a flash drive to get a copy.
