⚠️⚠️⚠️ Buildbot failure ⚠️⚠️⚠️Hi! The buildbot aarch64 Fedora Stable 3.14 (tier-2) has failed when building commit ab63a5a. What do you need to do:
You can take a look at the buildbot page here: https://buildbot.python.org/#/builders/1750/builds/607 Summary of the results of the build (if available): Click to see traceback logsNote: switching to 'ab63a5a510931e9d12eb67ca4d913be2be105ab2'.
You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by switching back to a branch.
If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -c with the switch command. Example:
git switch -c <new-branch-name>
Or undo this operation with:
git switch -
Turn off this advice by setting config variable advice.detachedHead to false
HEAD is now at ab63a5a510931 [3.14] gh-151126: Fix crash on unset memory error in `ctypes.get_errno` (GH-151382) (#151399)
