dpkg: error processing package linux-image-generic (–configure): dependency problems – leaving unconfigured

I had this issue just now. What I did was purge the errant package using dpkg in my case then update and force the reinstall:

sudo dpkg --purge linux-image-3.13.0-35-generic
sudo apt-get update
sudo apt-get -f install

python: uninstall python 2.7 install via source

To completely remove python you can execute:

rm -f /usr/local/bin/python2.7
rm -f /usr/local/bin/pip2.7
rm -f /usr/local/bin/pydoc
rm -rf /usr/local/bin/include/python2.7
rm -f /usr/local/lib/libpython2.7.a
rm -rf /usr/local/lib/python2.7

You might also have to do

rm -f /usr/local/share/man/python2.7.1
rm -rf /usr/local/lib/pkgconfig
rm -f /usr/local/bin/idle
rm -f /usr/local/bin/easy_install-2.7
