[FIXED] IPython notebook 2.3.0 on Fedora 21 cannot find FontAwesome

Issue

Looking for help trying to tell IPython notebook where to find the fontawesome fonts on Fedora 21. They are apparently packaged separately under /usr/share/font-awesome-web. Is there some configuration for this? Failure to find/serve the font is causing the buttons not to render correctly in the browser...

In the browser, I'm getting a 404:

[02:50:16.296] downloadable font: download failed (font-family: "FontAwesome" style:normal weight:normal stretch:normal src index:2): status=2147746065 
source: http://192.168.56.88/static/fonts/fontawesome-webfont.ttf?v=4.1.0 @ http://192.168.56.88/static/style/style.min.css?v=84c99f996b473c651c7a92702ce5cd33

And in the terminal where I'm running the notebook server, there's really not much more information:

Solution

I just run into this problem myself today. The file /usr/lib/python2.7/site-packages/IPython/html/static/style/style.min.css of the python-ipython-notebook-2.3.0-1.fc21.noarch package has wrong references to font awesome files. A quick and dirty fix is:

cd /usr/lib/python2.7/site-packages/IPython/html/static
sudo ln -s components/font-awesome/font fonts

It would be best to signal with bug of the python-ipython-notebook in RedHat bugzilla, I will do that if I get some spare time.
