Hello Adrian,

from where did you install the GNU health module(s)?

They aren't yet packaged for Debian/Ubuntu to my knowledge. The tryton server tells in the traceback, that you are missing some modules, that have to be installed first.

The current GNU healh modules need Tryton version 2.4, which was uploaded to Debian experimental due to the upcoming freeze. You can get it from there.
