> Oh hmm, sorry. I assumed that you did [79ed11f](https://github.com/apache/airflow/commit/79ed11f9147483c4b2f6cc99d5a3e41e89d92968) manually. @ashb I think what *might* be the reason - the build assumes that the docker engine is unpopulated when it starts (we have the `docker system prune --all` as the prerequisite step - which was there for a good reason - one of them was that it always pulled latest versions of python images before the build. Removing the "cleanup" step might have changed the behaviour and some of the pre-populated images (notably python one) might be causing different behaviour (for example last week keys expired in old python images and they were re-populated by python team). Not sure yet if that is the case but this might be the reason why cache is not actually used during the build (It will not be used if your local python version is different than the one used to build the base image). ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
