Ubuntu

how can I remove older kernels?

Asked by Manolis Vitsaxakis

I have a DELL with preinstalled 14.04 and when I used ¨python-mechanized¨ to produce a signature for a forum it told me that there are more than 1 kernel installed.
How can I check that and how do I remove older kernels?

Thank you
