Package: docker-compose
Version: 1.25.0-1
Severity: normal

Hi,

When I try to run the "exec" command of docker-compose on any running
container, Python throws:

WARNING: The b'PATH' variable is not set. Defaulting to a blank string.
Traceback (most recent call last):
File "/usr/bin/docker-compose", line 11, in <module>

raise ValueError(
ValueError: env cannot contain 'PATH' and b'PATH' keys

Downgrading to 1.21.0-3 solves the problem so I don't know if the issue is with
docker-compose or some dependencies.

Let me know if you need any other information about this problem.

Greets.

Does this still happen with the latest version?
