admin server not starting

[accheddu]

Hi, the admin server is not working apparently on ubuntu 16.04.

This is the error in the log:

Any clue about it?

You may have a version of more-itertools installed that is not
compatible with python 2.7.

https://github.com/erikrose/more-itertools/issues/272

Looks like versions 6 and above are not compatible but may be installed
by old versions of pip.

Thanks.

Indeed I have pip 8.1.1 installed and I was not able to build from source lately.

The weird thing is that a paid image from Google Cloud Market had the same problem.

This solved the error:

pip install "more-iter==4.3.0"

But it turn out that tornado was on a wrong version as well.

To this:

pip install "tornado==4.2"
