My /boot/ partition is full and I can't purge old kernels, I've been trying the suggestions here but no luck How do I free up more space in /boot?

dpkg -l linux-image-\* | grep ^ii

sudo apt-get update suggests I Try 'apt-get -f install' with no packages (or specify a solution).

All I get for my efforts is this:

The following packages have unmet dependencies.
 linux-image-extra-4.4.0-93-generic : Depends: linux-image-4.4.0-93-generic but it is not going to be installed
 linux-image-extra-4.4.0-96-generic : Depends: linux-image-4.4.0-96-generic but it is not going to be installed
 linux-image-generic : Depends: linux-image-4.4.0-96-generic but it is not going to be installed
                       Recommends: thermald but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

sudo apt-get autoremove returns

sudo apt-get autoremove
Reading package lists... Done
Building dependency tree
Reading state information... Done
You might want to run ‘apt-get -f install’ to correct these.
The following packages have unmet dependencies.

E: Unmet dependencies. Try using -f.

apt-get autoremove.

As you worked out yourself, you will have to remove an old kernel manually first.

After running apt-get autoremove, your boot partition should be much emptier. I personally have a root cron to do that weekly so I don't get into your situation.

Make sure you do an update and upgrade too to resolve the dependency issues, then reboot to start the new kernel.

Once you have run out of space and have half installed packages, apt gives up. You have to remove some packages with sudo dpkg -r xxxxx to get some free space, then you can have apt remove more.
