@alessfg Hello, could we run another build ? Upgrade scenario might now be fixed, hopefully

Hey there! I see you closed this PR -- the tests were failing due to Ansible Lint running into some edge dependency issues. I'm currently trying to update the role to the latest version of Ansible Lint (as well as fix other issues stemming from the latest couple NGINX updates), but once I get those fixes in, I can try merging this PR if you want to reopen it. Plus, this PR should partially address #478 so that's an extra bonus.

Hello.
Sure I'd reopen it for another attempt the moment you get that fixed!
Thanks
