When I try trytond-admin -c trytond.conf -d training -u account_ca_gifi, I get an error:

(.venv) awes7@mydev:~/projects/training$ trytond-admin -c trytond.conf -d training -u account_ca_gifi

The above exception was the direct cause of the following exception:

Your custom module account_ca_gifi has invalid record in the XML files. It is referencing a balance_sheet that does not exist.
It looks like it is an old version of an account chart that is no more compatible with the server series.
