RuntimeError: set_wakeup_fd only works in main thread of the main interpreter #645

Open freyes opened 7 months ago

freyes commented 7 months ago

The PR #608 is introducing support for Juju 3.x, during the testing it was found that zaza is incompatible with python-libjuju>=3.2, which prevents using juju 3.2 and 3.3.

The stacktrace of the error is:

It seems this regression was introduced by https://github.com/juju/python-libjuju/commit/62a988fad7c574914c08a8ee9723f642ae7d5b80 part of python-libjuju>=3.2.2.
