If you've had some trouble getting econocalypse to build from source on Ubuntu Server 18.04.2, these steps worked for me. I can confirm that the qt wallet works under Xubuntu 18.04.2 in a virtual box using these steps. This may work for Debian 9.7 or 9.8, Ubuntu Server 18.10, and any of the gui flavors of Ubuntu 18.04.2 or 18.10. At this time they do not work with Ubuntu 19.04. Use at your own risk.
This worked like a charm for me with Ubuntu Mate 16.04 & 18.04. thank you!
