Subject: [devpi-dev] Need help, devpi-server upgrade problems.


I've got problems during upgrading devpi-server.

This is the output from pip list:

I've tried to upgrade to the newest devpi-server-2.2.2. No success - just a traceback. Than I created a fresh environment with older  devpi-server-2.2.0 version and used --export and --import options. Also no luck.

here is a part of the traceback:
