[Health] GNU Health Installation issue

[Paras Jasani]

New to Ubuntu and Tryton. I have been trying to install gnu health. I followed all instructions given in wiki page. When i try to boot the tryton server it gives the following error

address@hidden:~$ trytond
Traceback (most recent call last):
  File "/usr/bin/trytond", line 30, in <module>
    trytond.server.TrytonServer().run()
TypeError: __init__() takes exactly 2 arguments (1 given)


when i use tryton -c trytond
address@hidden:~$ tryton -c trytond

    with open(KNOWN_HOSTS_PATH, 'w') as known_hosts:
IOError: [Errno 13] Permission denied: '/home/gnuhealth/.config/tryton/2.2/known_hosts'

Can some please help me as its important to run the gun health module to take in the patient records.

Thanks
