Bug Description

Ubuntu: trusty 14.04

The python2 and python3 packages for the networkx library should (presumably) be co-installable, but currently contain a common set of files that cause whichever is installed second to fail.

python-networkx: 1.8.1-0ubuntu3
python3-networkx: 1.8.1-0ubuntu3

$ sudo apt-get install python{,3}-networkx
[ ... ]
dpkg: error processing archive /var/cache/apt/archives/python3-networkx_1.8.1-0ubuntu3_all.deb (--unpack):
 trying to overwrite '/usr/share/doc/python-networkx/examples/basic/read_write.py', which is also in package python-networkx 1.8.1-0ubuntu3

While the library is installed in /usr/lib/pythonX.Y/dist-packages in each case, both attempt to install (I think identical) documentation/examples to /usr/share/doc/python-networkx, causing the collision.

I assume either a python 2/3 independent documentation package is needed, or the python3 package needs to change the directory into which it installs documentation. There seem to be a number of other python3- prefixed directories in /usr/share/doc, so this wouldn't be unprecedented.

This bug was not present in Saucy (python-networkx 1.7-2, python3-networkx 1.7-2), in which the python3 version contains no documentation.

We are waiting for version 1.9 package to be included, meanwhile a workaround can be done:

do it in two phases:
install python-networkx (if not done already):
sudo apt-get install python-networkx
then you will need to move python-networkx doc:
sudo mv /usr/share/doc/python-networkx /usr/share/doc/python2.7-networkx
so the documentation for python-networkx will be available from /usr/share/doc/python2.7-networkx
don't forget to manually remove this directory if you remove/purge package

then:
sudo apt-get download python3-networkx
sudo dpkg -i --force-download python3-networkx

then the documentation for python3-networkx, will be splitted in two parts:
/usr/share/doc/python3-networkx and /usr/share/doc/python-networkx

Not very nice but it allows you to install both of them.
If you remove python-networkx, il will remove the python3-networkx, so you may want to copy documention if you want to keep python3-netwokrx documentation
sudo mv /usr/share/doc/python-networkx /usr/share/doc/python3-networkx
if you do so, don't forget to manually remove this directory when removing python3-networkx

Will this be fixed in Ubuntu 16.04? Debian Jessie already has version 1.9, so, please fix this.
