futures<=2.2.0,>=2.1.6

What version of futures is installed?  Run 'pip show futures'.

I think this is being pulled in by an uncapped dependancy in swiftclient:

I know the devstack/juno install worked on Friday last week, so something 
changed over the weekend.

Ahh perhaps this https://review.openstack.org/#/c/212652/ ?

My solution would be to cap futures in swiftclient but I don't knwo that is 
correct.

Yours Tony.

Yeah, g-r for stable/juno caps python-swiftclient at 2.3.1 [1] and that version has an uncapped dependency on futures [2].

You'd have to get a stable/juno branch created for python-swiftclient from the 2.3.1 tag probably, then cap futures and release that as 2.3.2. You'd also have to raise the cap on swiftclient in g-r stable/juno to python-swiftclient>=2.2.0,<2.4.0.
