Related to this issue https://bugs.python.org/issue34651, our Bareos libcloud plugin cannot be run with Python > 3.7. We are using subprocesses in a C-subinterpreter environment. Is there a way to circumvent rewriting our code completely? |

Could you please post the error message and either post a minimal example or give us a link to your code? |
