Hi,
The LTS Release 6.0 of Tryton is available on openSUSE for Leap and Tumbleweed. To install it, you need to add the respective repository to your system, e.g. for Leap 15.3:
zypper ar -f -p70 https://download.opensuse.org/repositories/Application:/ERP:/Tryton:/6.0/15.3/ Tryton6
Afterwards you can install Tryton and its modules using zypper or the graphical frontend YaST.
Additionally it comes with a setup-program openSUSE-trytond-setup to make the jumpstart for less experienced users easier.
Have fun…
