novnc failed to start due to unexpected keyword argument

[DWang]

Hi everybody,

I'm new to DevStack and during my installation of icehouse devstack, some error arose like this:
"
...
ls /opt/stack/status/stack/n-novnc.failure
2014-08-25 07:49:55.739 | + failures=/opt/stack/status/stack/n-novnc.failure

"

Then I went to the corrispond screen to check what is wrong:

"

I don't what's going on and how to fix it, anyone have any idea?
THX!

Looks like a version issue as mentioned in

What platform are you running on?

[DWang (darren-wang)]

ubuntu 14.04.1 Desktop

@Ian Wienand
Thx Ian, I've solved this problem.

I uninstalled websockify 0.6.0(automatically installed latest version) and reinstalled websockify 0.5.1, then this problem just gone.

[Dean Troyer (dtroyer)]

We are actually about to bump the minimum required version of wesockify to 0.6.0 for the Juno release. Are you on an older Nova release, say icehouse maybe?

[DWang (darren-wang)]

Yeah, in icehouse release

I believe this is fixed upstream, please reopen if otherwise.
