Updating Ubuntu

[Peter Goggin]

I have ubuntu installed on an X61s laptop. The update manager has 
identified a number of updates but when I try to install the updates I 
get the following message:

The upgrade needs a total of 77.6 M free space on disk '/boot'. Please 
free at least an additional 4,664 k of disk space on '/boot'. Empty your 
trash and remove temporary packages of former installations using 'sudo 
apt-get clean'.

I have run 'sudo apt-get clean ' and emptied the rubbish bin but this 
has made no difference. i still get the same message.

The bin folder contains 155 items occupying 9.5 Mb Total free space is 
74 Gb.

What do I need to do to get the updates to work?
