Hi,
I have many dependency conflicts after installing a module.
Probably these conflicts apprears during an upgrade to trytond 6.0.2 I’ve made before.
Tryton seems to work normally. But I’m not sure what I sould do to normalise the situation now.

In the about section the client version is 5.8.
What would you recommend to do in such a situation?
I havn’t run the `trytond-admin --update-modules-list` yet, or activated the module.
Downgrade packages? Ignoring?

This error is due to an instalation of packages of mixed series. In your case it seems you have installed modules from 5.8 series but also for 6.0 series.
You should remove (using pip) all packages of the not desired version and install the required ones.
If you have a virtualenv, probably it’s easier to remove it and reinstall all the packages of the desired serie.

If you have a virtual environment you can use `pip install --upgrade trytond-==5.8.*` and pip should install the right packages. It maybe also will work in a default environment.

Tanks, using pip I’ve succesfully downgraded all packages to 5.8.
