This is what I did on Ubuntu 16.04.4 LTS
I checked my version
lsb_release -a
Then checked the drive

Check which kernel you are running:
uname -r 4.4.0-116-generic
Check for installed images that may no longer be necessary
sudo dpkg --list 'linux-image*'|awk '{ if ($1=="ii") print $2}'|grep -v `uname -r`
linux-image-4.4.0-112-generic
linux-image-4.4.0-91-generic
linux-image-4.4.0-93-generic
linux-image-4.4.0-96-generic
linux-image-extra-4.4.0-112-generic
linux-image-extra-4.4.0-91-generic
linux-image-extra-4.4.0-93-generic
linux-image-extra-4.4.0-96-generic
Since we’re running 116 we want to get rid of everything except the second to last one in relation to the current kernel.
sudo rm -rf /boot/*-4.4.0-{91,93,96}-*
Then run the following, which took about 3 minutes
sudo apt-get install -f
Then check the drive again
