I think we're getting the same error:

"drush updb" gives:
[error] Search API Autocomplete requires this module and version. Currently using
Search API version
(Currently using Unresolved dependency Search API (Version >= 8.x-1.20 required)
)

Thanks for reporting this problem!
That’s really a doozy. Off the top of my head, I can’t venture a guess why this would happen.
Are you able to obtain a stack trace for the error? (It is thrown in \Drupal\search_api\Entity\Index::getDatasource().) That would help a lot.

(In the future, however, please don’t post config YAML as a comment, but instead use an attachment.)

@w01f: That seems like an entirely different problem, namely that you have Search API installed via Git and Drupal unfortunately does not handle that correctly. It therefore incorrectly reports a dependency version conflict.
