Aditional info

The same pipeline worked some days ago. When I run today, it doesn't work.  I guess it has something to do with a new version of Docker

The version used by the Microsoft Hosted environment is as follows:

We have the same issue.

[smisch]

We encountered the same issue in our own images. The root cause was the installation of docker or docker-compose via pip. During the installation the urllib3 library was updated to 2.0.0, which is not compatible with the request lib version that came with the OS.

Following this stackoverflow answer, reinstalling the request library via pip successfully downgraded the urllib3.

Again, we had this in our own images on gitlab. Hope that still helps you!

Edit: Found the actual reason. urllib3 just released version 2.0.0, so any package that depends on e.g. >=1.25.0 will now install 2.0.0 and break the request library. See also.

Thank you a lot @smisch! That's worked!

I added a step to manually install that dependency

pip install -U iotedgedev pyOpenSSL==22.0.0 urllib3==1.22 requests

pyOpenSSL==22.0.0 to solve the issue described here
urllib3==1.22 requests to solve this new issue that @smisch describes

@jdiazfernandez your fix worked, fantastic!
