Was going to upgrade a module until this error showed.

Traceback (most recent call last):

Should I install orchange something?

We already told you two times to check the changelogs. You should really do that!

In the changelog for the 6.4 release there is this entry:

* Use a set for field's depends

Python’s sets have a different API than the list. You must update your code to follow the set API.

I see from your traceback that you are using a gnuhealth module.
Latest gnuhealth version works on tryton 6.0 series but it seems you are using a more recent series. If you want to use gnuhealth modules you should keep with 6.0 series.

Remember: All tryton components (server and modules) must be from the same series (its first two digits of the version must be the same).
