Description:

python-openstackclient depends on python-cliff, which in turn depends on python-cmd2. The versions of these packages which are currently being installed do not play nice together:

Any invocation of openstack client fails to properly load any of its connector plugins. Running the comamnds in debug mode reveals the version mismatch:

output in normal mode:
$ openstack help

...
Commands:
Could not load EntryPoint.parse('access_token_create = openstackclient.identity.v3.token:CreateAccessToken')
Could not load EntryPoint.parse('address_scope_create = openstackclient.network.v2.address_scope:CreateAddressScope')
...
[plus several dozen similar failures]


output in debug mode

$ openstack --debug help

...
Commands:
Could not load EntryPoint.parse('access_token_create = openstackclient.identity.v3.token:CreateAccessToken')
