I second ~grey's assertion. I installed Wily 15.10 only a few weeks ago
and accepted the default /boot partition size suggested for use with LVM
and today was unable to perform a routine package upgrade due to a lack
of free space on /boot. I was able to work around the problem by first
listing installed kernel versions:
$ dpkg -l linux-image-\*|grep ^ii
ii linux-image-4.2.0-16-generic 4.2.0-16.19 amd64 Linux kernel
image for version 4.2.0 on 64 bit x86 SMP
ii linux-image-4.2.0-21-generic 4.2.0-21.25 amd64 Linux kernel
image for version 4.2.0 on 64 bit x86 SMP
ii linux-image-4.2.0-22-generic 4.2.0-22.27 amd64 Linux kernel
image for version 4.2.0 on 64 bit x86 SMP
ii linux-image-4.2.0-23-generic 4.2.0-23.28 amd64 Linux kernel
image for version 4.2.0 on 64 bit x86 SMP
ii linux-image-extra-4.2.0-16-generic 4.2.0-16.19 amd64 Linux kernel
extra modules for version 4.2.0 on 64 bit x86 SMP
ii linux-image-extra-4.2.0-21-generic 4.2.0-21.25 amd64 Linux kernel
extra modules for version 4.2.0 on 64 bit x86 SMP
ii linux-image-extra-4.2.0-22-generic 4.2.0-22.27 amd64 Linux kernel
extra modules for version 4.2.0 on 64 bit x86 SMP
then identifying the running kernel
$ uname -r
4.2.0-22-generic
then purging old kernel pax
$ sudo apt-get purge linux-image-4.2.0-{16,21}
and finally completing package upgrades
$ sudo aptitude update && sudo aptitude upgrade

Title:
update-initramfs should produce a more helpful error when there isn't
enough free space
Status in initramfs-tools:
Confirmed
Status in initramfs-tools package in Ubuntu:
Triaged
Bug description:
Binary package hint: initramfs-tools
When generating a new initramfs there is no check for available free
space, subsequently its possible for update-initramfs to fail due to a
lack of free space. This is resulting in package installation
failures for initramfs-tools. For example:
Setting up initramfs-tools (0.98.8ubuntu3) ...
update-initramfs: deferring update (trigger activated)
Processing triggers for initramfs-tools ...
update-initramfs: Generating /boot/initrd.img-2.6.38-8-generic
gzip: stdout: No space left on device
E: mkinitramfs failure cpio 141 gzip 1
update-initramfs: failed for /boot/initrd.img-2.6.38-8-generic
dpkg: error processing initramfs-tools (--configure):
subprocess installed post-installation script returned error exit status 1
WORKAROUND:
Remove unused kernels using computer janitor (not in repositories for
14.04 or later) or manually free space on your partition containing
the /boot file system.
