Yes, I believe that was the decision made at DebConf 22. > I believe there are many packages that will > FTBFS with Python 3.11 as default (i.e., packages that use only the > default Python). Was there an attempt to rebuild the archive with that > setting? A typical test rebuild will only catch FTBFS in dependency level one (and maybe level two) of the transition tracker. In the higher levels, you'll get false positives due to failed imports of the modules that need rebuilding. Similarly, uploading python3-defaults to experimental and checking for autopkgtest failures will also result in false positives. For reference, the python3.11-add tracker lists 594 packages (excluding unknowns), and the python3.11-default tracker lists 351. With the ben files currently used in the trackers, packages still red on the first tracker also appear on the second. For what it's worth, an incremental test rebuild of the first three dependency levels was done in an Ubuntu PPA [3]. Roughly 80% of the packages involved in the python3.11-default transition were tested, and roughly 80% of the builds were successful. All build failures are counted here, including dependency-wait and architectures that have never had a successful build. A similar test rebuild was done in January 2022 for Python 3.10 [4] and I think the numbers indicate we are in a very similar state.
