Here's the view from conjure-up.log, fwiw:

This is an issue with pyyaml and python 3.7:

yaml/pyyaml#126

I'm unclear why the pyyaml-4.2b2 resource wasn't installed for me, but if i install pyyaml manually, conjure-up works:

$ pip3 install pyyaml==4.2b4

[adam-stokes]

Very odd, we have the beta referenced in the formula.

I'll need to see if we're missing something the tests aren't catching

[adam-stokes]

Looks like pyyaml 3.13 will be released with 3.7 support, so we'll want to update the brew formula when that is released, hopefully today or tomorrow

Still having this issue as of today with a fresh install of Ubuntu 16.04 Server LTS, with current snaps for lxd and conjure-up, deploying kubernetes-core on localhost.

[kwmonroe]

Oof, sorry I left this open so long. Confirmed fixed in conjure-up 2.6.0 on macos. This fixed me a few months ago:

Homebrew/homebrew-core@6bc6dd6

@spjz, this was an issue with homebrew/macos deps, so it won't be the same root cause for ubuntu.
