Disk full at /boot of Ubuntu system after several months system update as follow

It is really inconvenient to maintain this issue.  Is Ubuntu default boot directory size 200MiB? Anyway, the following commands could remove unused linux-image at /boot


# uname -r
3.2.0-40-generic
# dpkg --list 'linux-image*'
