I was working in tryton version 5.0 from a long time in a virtualenvironmentA on a Linux server and today i decided to work with two versions, so i have gone and i installed tryton version 6.0 in another virtual environment, but Unfortunately, after installing tryton and trytond with those two commands:
i was about seeing my version in this virtual environement to confirm that everything is good with the command tryton --version
response was:
Unable to init server: Could not connect: Connection refused
(tryton:12200): Gtk-WARNING **: 10:55:20.878: Locale not supported by C library.
Using the fallback 'C' locale.
Unable to init server: Could not connect: Connection refused
(tryton:12200): Gtk-ERROR **: 10:55:21.084: Can't create a GtkStyleContext without a display connection
and lastly when i have gone to my version 5.0 to see that the environment has not be affected , but the same error displayed when i put tryton --version and trytond version become 6.0 not 5.0.
what does mean this error, and how i can fix my previous version to back to her first version and i want to know my work it can be affected if i will update now my database in the previous version!
And what about the server trytond that exist in another virtual environment version 5.0 it becomes 6.0, is it normal and if i will update my database over there in my version 5.0, it will be affected ?
To me, it seems you forgot to activate your virtual environment, so you installed tryton version 6.0 globally. To test that, just make sure you don’t have any virtual environment active and execute the command trytond-admin --version. If it comes back with information, you have globally installed tryton.
The best way I can think of is to remove it again (with pip) and see if everything is ok with your 5.0 environment. Then create a new virtual environment for 6.0 and activate it and install version 6.0.
Also you cannot run both version at the same port. Default this port is 8000, but one of the version should run on another port e.g. 8060. You have to set that up in your trytond.conf
When upgrading from 5.0 to 6.0 I personally will do the small steps, so go from 5.0 to 5.2 and so on until 6.0
yeah unfornatully i found that the trytond was installed globaly , version 6.0.0 , which command i should use to unistall this version 6.0.0 and keep my old version 5.0
basically the commands you have used but now using uninstall. I think when you have uninstalled tryton, you will be able to run tryton version 5.0 from within you virtual environment again. Because you run tryton version 5 in a virtual environment, this installation should not be affected but Python first takes the global packages before using the virtual environment one.
BTW, if you want to run more version alongside each other, make sure you also use separate databases as well.
Well it’s my personal preference to do it one step at a time because I’m always walk into trouble when doing big steps
Am using linux i go to my virtual environement by workon name_project; otherwise again when i update my database there was another error in my version 5.0 :

Ah, I see, you didn’t install Trytond in your environment with pip. Looking at your error, the problem seems to be in a package called csb43 and it looks like @pokoli can help you with that.
