Return to Service
Run this command as root:
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*
(let it run to completion)

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