[Python-modules-team] Bug#793024: python-docker: Requires websocket-client >= 0.32

[Felipe Sateler]

Package: python-docker
Version: 1.3.0-1
Severity: serious
Justification: renders package unusable

Hi,

The new 1.3.0 has a requirements.txt with websocket-client >= 0.32.0,
which is not satisfiable in debian. Example trace from docker-compose:
