apt-get remove --purge $(dpkg -l 'linux-*' | sed '/^ii/!d;/'"$(uname -r | sed "s/$.*$-$[^0-9]\+$/\1/")"'/d;s/^[^ ]* [^ ]* $[^ ]*$.*/\1/;/[0-9]/!d')

or use apt-get to purge packages using package name/version numbers:

apt-get --purge remove linux-image-3.11.0-1*

(let it run to completion)

apt-get --purge remove linux-image-extra-3.11.0-1*

Dpkg should now output installed kernels, and it should match the version of the running kernel.
