I recently had to reinstall my system because I  chose to ignore smartd's emails nagging me about unrecoverable errors a bit too long.
The system disk that inevitably died before I could grab an image provided me with an opportunity to install the latest & greates Ubuntu LTS release (16.04), and yes, I know, Ubuntu (server) is not a supported platform.

How hard can it be right? Install OS, install Domino, Traveler and fix packs, been there, done that etc.
Well... I got as far as installing Domino 9.0.1 and Traveler 9.0.1 and then things got interesting.
