Pipenv gets blocked while running with Docker in Gitlab

[Peque]

I created this simple project in Gitlab:

https://gitlab.com/PequeX/deleteme

With a Pipfile that installs only a couple of packages:

[[source]]
name = "pypi"
url = "https://pypi.org/simple"
verify_ssl = true

[dev-packages]
pytest = "*"

[packages]
requests = "*"

[requires]
python_version = "3.7"

And a very simple .gitlab-ci.yml file:

image: peque/python-devel

before_script:
  - pipenv sync --dev

python36:
  script:
    - pipenv run pytest

There is also the autogenerated Pipfile.lock file. Which I will not paste here as it is not very interesting.

Now, the problem is Gitlab seems to get blocked when calling pipenv sync:

https://gitlab.com/PequeX/deleteme/-/jobs/171273142

There is no output printed on the log and no error. It just gets blocked forever. And then, eventually, it timeouts (because Gitlab would not let you run a pipeline forever).

Maybe related: #3534

Will try that workaround.

It seems the workaround in #3534 does avoid the block at pipenv sync.
