ld: cannot find -lnl-route-3

[IamSierraCharlie]

Hello, I'm seeing the following error:

Trying to install with python3 3.5.2 (default, Nov 17 2016, 17:05:23) [GCC 5.4.0 20160609]

Admittedly, I'm on Ubuntu 16.04 - not sure if that is a significant issue with this version of python-ethtool This is the last bit of the install attempt after running

sudo -H python3 setup.py install

x86_64-linux-gnu-gcc -pthread -shared -Wl,-O1 -Wl,-Bsymbolic-functions -Wl,-Bsymbolic-functions -Wl,-z,relro -Wl,-Bsymbolic-functions -Wl,-z,relro -g -fstack-protector-strong -Wformat -Werror=format-security -Wdate-time -D_FORTIFY_SOURCE=2 build/temp.linux-x86_64-3.5/python-ethtool/ethtool.o build/temp.linux-x86_64-3.5/python-ethtool/etherinfo.o build/temp.linux-x86_64-3.5/python-ethtool/etherinfo_obj.o build/temp.linux-x86_64-3.5/python-ethtool/netlink.o build/temp.linux-x86_64-3.5/python-ethtool/netlink-address.o -lnl-3 -lnl-route-3 -o build/lib.linux-x86_64-3.5/ethtool.cpython-35m-x86_64-linux-gnu.so /usr/bin/ld: cannot find -lnl-route-3 collect2: error: ld returned 1 exit status error: command 'x86_64-linux-gnu-gcc' failed with exit status 1

I can't find anything on this error searching (or I'm not searching for the right thing. My knowledge in python is not the best. Appreciate any feedback you might be able to offer...

[IamSierraCharlie]

Sorry - I've jumped the gun

this is resolved by running sudo apt install libnl-route-3-dev

hopefully this helps someone else running Ubuntu 16.04.3 LTS

We might want to document this.

For the record, and to help with documentation, I ended up with the same error, but before that I was seeing the follow:

The directory '/home/maurosr/.cache/pip/http' or its parent directory is not owned by the current user and the cache has been disabled. Please check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag.

then I installed libnl-3-dev, and saw the same error of this issue, fixed with the same libnl-route-3-dev
