Update impossible after upgrade to PDM 1.1.1

[jvliere]

After we upgrade from PDM 1.0 to 1.1.1 it's seems impossible to run de updates.
We have a valid Base subscription and with the pdm-enterprise repository, we get the following error:

It's only possible to update with the no-subscription repository.
What are we doing wrong?
