Hey, I get this error everytime I try to run ./stack on any branch:

You need to upgrade the package keystoneauth1, because the version that you have in your system is: 2.4.3 And Glance needs version: >=2.16.0.

Try the following:

pip install 'keystoneauth1>=2.16.0'

But I think you will have more error like that in the future.

I have had the same erros with Devstack, after rebuild it multiple times, The only solution was to reinstall my enviroment and start again, but maybe you have more luck than me.
