Hi,

For some reason I cannot base my image on the `build` version of the Debian stretch base image:

```dockerfile
FROM balenalib/%%BALENA_MACHINE_NAME%%-debian-python:3.7.4-stretch-build

```

This results in the deploy hook error:

> manifest for balenalib/raspberrypi4-64-debian-python:3.7.4-stretch-build not found

I have to switch to default (`run`) version:

```dockerfile
FROM balenalib/%%BALENA_MACHINE_NAME%%-debian-python:3.7.4-stretch-run

```

which works, but I have to preinstall required packages, etc.  
Am I missing something here?

Thanks!

I have pinged our main base-images team to see if there is something out of place 👍

Hi @blazejewicz , some feedback from our base-images team here. There is a problem when compiling python-dbus (a package we ship in build variant) with python 3.7.4. Could you use the previous version `3.7.3-stretch-build` or stay with the `3.7.4-stretch-run` while this is being fixed?

@mikesimos  
Yes, it helped. That’s fine to use 3.7.3, I’d like to play with multi stage builds, hence I’ve tried to use `build`/`run` versions.

Thanks!
