Package: python3-taskflow Version: 3.1.0-3 Severity: important Dear Maintainer,
*** Reporter, please consider answering these questions, where appropriate *** * What led up to the situation? I was trying to set up openstack/cinder for self-teaching purpose from buster Debian packages. I got an error when trying to create a cinder volume from openstack web interface. This is the relevant extract from cinder-api logs: 1d035f8b786d - default default] Caught error: <class 'AttributeError'> 'OrderedDiGraph' object has no attribute 'nodes_iter': AttributeError:
