This one is written because to install Keepass2 successfully on Ubuntu 15.04 you need to read and search through at least 5 different sources. So without further ado:
Add ppa’s for Keepass indicator plugin:
sudo add-apt-repository ppa:dlech/keepass2-plugins sudo add-apt-repository ppa:dlech/keepass2-plugins-beta sudo apt-get update
Second one contains updated version with solved problem of missing libmagickwand5 dependency.
