Hello fellow friends,
I did an update to get to the most recent 6.8 modules and updated pip packages as well. Afterward, tryton will no longer start:
```auto
$ trytond -c trytond.conf -d 68-prod -vv

There is something wrong in your instalation, you have both 6.8 series and 6.4 series requirment.

Probably an update / install without activating your virtual environment? Maybe done in the past. Just uninstall all Tryton packages without any activated virtual environment. Also search the forum here, there should be a topic in which you’ve done that.

Unluckily not. I just found werkzeug system-wide, uninstalled it, but that didn’t help. Well, I managed to update to 7.0, so it’s not really serious.
Thank you anyway.
