I did a first peek at the jupyter packages and tried to build jupyter- core to see what was up with #1047824 "jupyter-core fails to build source after successful build".
However then I discovered that it depends on a version of pydevd < 2.11 and debian now has 3.1.0 in unstable, so it has an unsatisfiable build dependency. Upstream's release files for debugpy includes a vendored copy of pydevd. For the 1.8.2 release it looks like it includes pydevd 2.9.5. I tried building 1.8.2 with the embedded copy of pydevd removed and the tests immediately crashed without making much progress at all. I tried again keeping the embedded copy of pydevd and for Python 3.12 the test runner reported: = 87 failed, 1092 passed, 38 skipped, 18 warnings, 83 errors in 361.96s (0:06:01) = Python 3.11 has some failures but I want to go to bed before it's going to finish.
