Cannot start on 16.04 with requests/SSL related import error

[Peter Levi]

Hello,

After latest update of Variety on Ubuntu 16.04, it won’t launch. I’m getting this when I try to launch in Terminal, can you help?

/usr/lib/python2.7/dist-packages/variety/__init__.py:105: PyGIWarning: Gtk was imported without specifying a version first. Use gi.require_version(‘Gtk’, ‘3.0’) before import to ensure that the right version gets loaded.

Many thanks,

Do you have python-openssl installed?
Can you try installing it and trying again please?

[Peter Levi (peterlevi)]

(sudo apt-get install python-openssl)

[Peter Sefton (peterjsefton)]

Thanks Peter, yes I appear to have python-openssl already installed,

[Peter Levi (peterlevi)]

Hm, yes, actually it seems to be something with urllib3: http://stackoverflow.com/questions/28987891/patch-pyopenssl-for-sslv3-issue

What's the output of these:
apt-cache show python-requests
python -c "import requests; import urllib3; print requests.__version__; print urllib3.__version__"

Sorry for the delay, here's the output,

[Peter Levi (peterlevi)]

Thanks! What about just
python -c "import urllib3; print urllib3.__version__"

[Peter Sefton (peterjsefton)]

It's

1.13.1

[Peter Sefton (peterjsefton)]

Variety now working perfectly, I used the following commands from the link you gave:

pip install requests==2.6.0

and

sudo easy_install --upgrade pip

Happiness! Thanks very much :)

`pip install requests==2.6.0` also worked for me. Variety had stopped working after a recent Ubuntu 16.04 upgrade.

[edA-qa (eda-qa)]

Actually I just did `sudo pip install --upgrade requests` without specifying a version.
