do-release-upgrade fail?

May be you got a warinning message when you execute do-release-upgrade:

Not enough free disk space

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

Because your /boot partition is filled with old kernels. You can easily remove the old kernels if you know which packages they came in.

# Mac OS X Lion introduced a new, iOS-like context menu when you press and hold a key
# that enables you to choose a character from a menu of options. If you are on Lion
# try it by pressing and holding down 'e' in any app that uses the default NSTextField
# for input.
#
# It's a nice feature and continues the blending of Mac OS X and iOS features. However,
# it's a nightmare to deal with in Sublime Text 2 if you're running Vintage (Vim) mode,
# as it means you cannot press and hold h/j/k/l to move through your file. You have
# to repeatedly press the keys to navigate.
