I currently can't update my release as there is not enough space on boot. I just have the one kernel version there, but seem to have both the Generic and Low Latency versions. uname -r just shows

3.8.0-32-lowlatency

ls -lah /boot shows

So what can I do to allow me to update? Apparently I need 174m on boot and am 40m short.
