Installing Bitcoin Armory on Ubuntu I installed Bitcoin Armory on Ubuntu 13.10. I get the following output when I try to run it:

root@cloud-server-07:/BitcoinArmory# python ArmoryQt.py
********************************************************************************

Does anyone have any idea why?
You should not run Armory as root. If you want to run armory as another user, pick a user other than root. You can use "sux" (which you can apt-get install) to become that new user.
