10:34:25 make: *** [Makefile:317: v8] Error 1Quick search on the error suggests that StrEnum requires Python 3.11. This has started today (above build (timer) and the one for nodejs/node#62136) so not sure if this is a new requirement or if it'll get reverted/changed in depot_tools.

This continues to fail almost two weeks later so doesn't look a inadvertent change on the V8 side.
Ubuntu 22.04 does have a
python3.11but it looks to be a rc build:I think we really ought to sort out the move to Ubuntu 24.04 for these machines, where the default python 3 is 3.12.

V8 CI is now running on the replacement Ubuntu 24.04 machines.
We have had to override
depot_toolsto recent version to gain Python 3.12 compatibility.
