Hi!
Decided to try gnu health and couldn't get through far enough to really get a taste of it...
I followed all the instructions related to installation and booting (ubuntu 12.10) on
http://en.wikibooks.org/wiki/GNU_Health/. It went well, but after starting tryton, pressing "Manage profiles" and entering localhost in "Profile Editor", instead of button "Create" I got "Could not connect to the server" message.
