Openstack/devstack Installation - The conflict is caused by: oslo-vmware 3.9.1 depends on suds-jurko>=0.6

I am trying to install devstack on Ubuntu 18.04, using the guide in https://docs.openstack.org/devstack/latest/.

Installation fails with the error,

ERROR: Cannot install cinder because these package versions have conflicting dependencies.

The conflict is caused by:
    oslo-vmware 3.9.1 depends on suds-jurko>=0.6
    The user requested (constraint) suds-jurko===0.6

To fix this you could try to:
1. loosen the range of package versions you've specified
2. remove package versions to allow pip attempt to solve the dependency conflict

ERROR: ResolutionImpossible: for help visit https://pip.pypa.io/en/latest/user_guide/#fixing-conflicting-dependencies

I have 2 python versions on the machine

stack@stack:~/devstack$ which python
/usr/bin/python
stack@stack:~/devstack$ which python3
/usr/bin/python3

Am I missing something here?

Best Regards,

J

Solution

  • Just install setuptools 57.5.0

    vim /opt/stack/requirements/upper-constraints.txt

    like this:

    #setuptools===58.2.0
setuptools===57.5.0

    It works for me.
