Getting conda package conflict on the CI

This happens on mac python 2.7 only: See: https://gitlab.idiap.ch/bob/bob.bio.face/-/jobs/126422

failed to get install actions, retrying.  exception was: The following specifications were found to be in conflict:
  - bob.bio.face==3.3.1b0=py27h0955f8a_6
  - bob.db.replay
Use "conda info <package>" to see the dependencies for each package.

If someone has some insights, it would be great.
