I have run the following command to remove old kernels:

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

and only the current kernel is now installed, which I have confirmed in synaptic and by checking my boot partition. However, when I run:

dpkg --list | grep linux-image

I get the following response:

rc  linux-image-3.13.0-30-generic                         3.13.0-30.55                                        amd64        Linux kernel image for version 3.13.0 on 64 bit x86 SMP

Probably not a problem, but just wondering why versions -30 and -32 are reported as present. Can it be rectified?

TIA
