[Health] GNU Health on Debian

[Christoph H. Larsen]

Sorry Folks,

I did a quick search, but not much luck, and zero capacity, but need a
quick fix urgently.
Zero problems with upgrading of GNU Health on FreeBSD, but espite total
de-installation, I get, using pip with Debian the following:
-----------------------------------------------------------------------
Traceback (most recent call last):
  File "/usr/local/bin/trytond", line 104, in <module>

    import _thread
ImportError: No module named _thread
-------------------------------------------------------------------------
The same error occurs with FreeBSD, if I do not uninstall the previous
version, but Debian seems to be resistant to this, and the error persists.

Any thoughts? Sorry again for this flimsy request, have a plane to catch
out of Afghanistan! Thanks a million!!!
