small /boot (as created for full-disk encryption) confuses update-manager

Bug Description

Every time a kernel update comes in, the update-manager scolds me for not having enough disk free on /boot. I try to autoremove everything I can, but in the end `sudo apt-get dist-upgrade` does the upgrade with no problems.

Separately from why the installer gave me such a teensy /boot (doesn't seem future-proof given the trends for kernel sizes), why can't update-manager work out the upgrade?

Not to be confused with bug 1389620, where autoremove would leave enough space but Software Updater doesn't suggest it.

Also, where would I file the bug against the installer part that made my /boot so teensy?

/dev/sda2 237M 141M 84M 63% /boot
/dev/sda1 511M 3.4M 508M 1% /boot/efi

I think this bug should be considered of high importance as it is a security risk because security updates can not be installed.

It happened to me on a clean install with default full-disk-encryption partitioning within about 2 months of use with a 1TB disk; so I'm guessing the 3 people showing as affected by this bug is the tip of the iceberg - or maybe most people using full-disk-encryption avoid using the standard software updater.

Running `apt-get autoremove --purge` doesn't appear to free up enough disk space for software-updater to work either. Thanks for the tip using `apt-get dist-upgrade`, that worked OK for me too.

Not sure if using dkms, but if so may be related to bug 1515513
