Debian 12 (bookworm) and non-LTS Ubuntu 23.04 (lunar) are going to disallow `sudo pip install` so anything you install with pip for use by their packaged Python interpreter will need to go into venvs. Here's the upcoming readme about it: https://salsa.debian.org/cpython-team/python3/-/blob/master/debian/README.ve... This has obvious implications for DevStack and Grenade, which currently install OpenStack services into the system environment for the distribution-packaged interpreter. Both bookworm and lunar will be released in a few months and people are going to end up using them for development systems, but at a minimum we're going to be forced to address this before we make Debian 12 or Ubuntu 24.04 LTS a targeted test platform for a release. There was an attempt to implement a solution 5 years ago when the writing was clearly on the wall that this would eventually happen. It may need some updates, but probably could serve as a good starting point: https://review.opendev.org/558930 -- Jeremy Stanley
