This is on stable/newton
, on Ubuntu 16.04 server.
Error message is:

stack@ubuntu-server-openstack:/opt/devstack$ pip list | ack keystoneauth1

I have also made sure to delete the pip cache rm -rf ~/.pip/cache
, but there does not seem to be one for this user.
How can the version conflict be resolved?
I solved this by using the default Vagrant script to set up a new vm under VirtualBox, upon which devstack installed just fine (stable/newton
). I then deleted the vm with the problem. I did not find the root cause of the misconfiguration with the python package versions.
