I would recommend you to show this command line:
$ sudo -u tryton trytond-admin ...

Another option is:
# su - tryton -s /bin/sh -c "trytond-admin ..."

sudo does not need the shell to work, and with su you can override the
user's default shell

sudo is common enough that even a non-sudo user could translate
its invocation into the "su" one (or assume that the command also ought to
work as root).
