At finishing stages of installing MISP-TAXII-Server, error message appears stating not supported cybox version for MISP with reequired for MISP-TAXII:

Installed /usr/local/lib/python2.7/dist-packages/misp_taxii_hooks-0.2-py2.7.egg
Processing dependencies for misp-taxii-hooks==0.2
error: cybox 2.1.0.12 is installed but cybox<2.1.1.0,>=2.1.0.13.dev1 is required by set(['stix'])

Is this specific to python2.7 only or python3 too?
Can Cybox be upgraded without impacting MISP as a required version to run?

How many times do I need to write these words?

STOP.

USING.

PYTHON.

It works if you use a version of python that isn't 17 years old

@FloatingGhost, I have a feeling you don't like Python 2 ;)

But indeed, MISP-STIX is STIX 1.2, which is Python3.

[trismegistusX]

Installed the supported version:
{"cybox": "2.1.0.13", "stix": "1.2.0.2", "success": 1, "mixbox": "1.0.2"}

Push worked:
INFO: Sending Inbox_Message to localhost:9000/services/inbox
INFO: Content block successfully pushed

Though MISP doesn't like it :)
STIX and Cybox libraries....OK
STIX library version....Incorrect STIX version installed, found 1.2.0.2, expecting 1.1.1.4
CYBOX library version....Incorrect CyBox version installed, found 2.1.0.13, expecting 2.1.0.12
MIXBOX library version....OK

Next instance will be only python3, I promise!!
