Yep, it affects me too, at least a couple of times a year. I'm using
home folder encryption only, not full disk encryption. When installing
Xubuntu, home-folder encryption is given as an option, so this bug will
affect those "ordinary" users who chose that option, not just us nerds.
So, I also think that when the "insufficient space on /boot" dialog is
shown, there should be an option for the user to have old kernel
versions removed automatically, because it's too difficult for the
ordinary user to remove them using via the command line.

Title:
Not enough disk space for kernel security update on /boot
Status in update-manager package in Ubuntu:
Confirmed
Bug description:
Hi all
I am using Ubuntu 12.10 and have just received the newest update
notification from the update-manager marked as security updates. (This
is NOT a release upgrade, but the regular security update)
The update-manager tells me now that there is insufficient space on /boot to install these updates.
The problem obviously is that too many kernels are installed: 3.5.0-17, 25, 26, 27, 28 and 30
Which leaves 27MB space:
Filesystem Size Used Avail Use% Mounted on
/dev/sda1 228M 190M 27M 88% /boot
Update Manager reports that it needs at least 33.2MB space for this
update:
"The upgrade needs a total of 33.2 M free space on disk '/boot'.
Please free at least an additional 5,520 k of disk space on '/boot'.
Empty your trash and remove temporary packages of former installations
using 'sudo apt-get clean'."
The hint in the message does not help for /boot.
While I can fix this myself, I believe that this is not acceptable for an average end user to research and fix.
Update-Manager should at least offer the option to remove old kernels (which it installed itself by security updates) in order for the security updates to proceed.
I found an answer on AskUbuntu.com (http://askubuntu.com/questions/142926/cant-upgrade-due-to-low-disk-space-on-boot) which will help fix the issue.
TL;DR:
-- 1 -- Release: 12.10
-- 2 -- Installed Version of update-manager: 1:0.174.4
-- 3 -- Expected:
Security update should be installed.
-- 4 -- Happened:
Failed because of insufficient disk space on /boot
(Too many old kernels previously installed and not removed by update-manager)
