lexicon.client.ProviderNotAvailableError: This provider (plesk) has required dependencies that are missing. Please install lexicon[plesk] first.

Error is misleading because of this part:

Please install lexicon[plesk] first.

it should be

Please install dns-lexicon[plesk] first.

I have a similar problem. The error doesn't specify what the real problem is here. I installed lexicon with the system's packet manager (apt on Ubuntu) which contains the logic for the provider I need. Something is missing, I get it, but what exactly? I'm unwilling to just do a dns-lexicon[something] if I can install system packages. It should list what dependencies are actually missing (e.g. describe the actual problem) and not present half-baked solutions.
