!!! wow, so much, how could this happen ?

And then:

uname -r

Trials to purge unused images:

apt-get purge linux-image-4.4.0-59-generic

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:

 linux-image-extra-4.4.0-59-generic : Depends: linux-image-4.4.0-59-generic but it is not going to be installed

 linux-image-extra-4.4.0-75-generic : Depends: linux-image-4.4.0-75-generic but it is not going to be installed

 linux-image-generic : Depends: linux-image-4.4.0-75-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).

Anyone got an idea?

Removing old kernels to free space in `/boot` partition

If your system is running using an old kernel (usually the newest kernel boots by default) you should boot from the newest kernel installed, which seems to be linux-image-4.4.0-72-generic in your case.

Select it from the GRUB menu (hold or repeatedly press Shift during boot if GRUB doesn't show at all).

When you have booted from your newest kernel, first run sudo apt-get -f install, trying to fix the unmet dependencies issues, if it works go on with any of the first two method below; if it fails jump to manual package purge.

The apt way

Try to correctly manage the space issue with apt:

Run sudo apt autoclean && sudo apt autoremove, apt should correctly manage removing all old-kernels and related packages if you haven't messed too much with it.

Using purge_old_kernels from byobu package

If the apt way doesn't work or it doesn't remove enough space:

Install byobu running sudo apt install byobu.

Then run sudo purge-old-kernels, which should remove old kernels in a cleaner way than directly purging packages.

Manual package purge

If any oh the above worked:

Purge the oldest (not running) kernel with sudo apt-get purge linux-image-4.4.0-21-generic && sudo update-grub.

Reboot and boot from the newest kernel available.

Run sudo apt-get -f install.

Run sudo apt update && sudo apt full-upgrade.

Reboot using your newest kernel.

Clean older kernels, via The apt way and/or _purge_old_kernels_.

The dpkg way

As a last resort, you can try to do it in the dpkg way which isn't the safest.

Run from your terminal (running from your newest installed kernel):

echo $(dpkg --list | grep linux-image | awk '{ print $2 }' | sort -V | sed -n '/'`uname -r`'/q;p') $(dpkg --list | grep linux-headers | awk '{ print $2 }' | sort -V | sed -n '/'"$(uname -r | sed "s/([0-9.-]*)-([^0-9]+)/1/")"'/q;p') | xargs sudo apt-get -y purge

Borrowed from this response.

Reboot your system and run sudo apt-get -f install

Do a full upgrade with sudo apt update && sudo apt full-upgrade.

Reboot if needed (new kernel¿?) and go with the apt way: sudo apt autoclean && sudo apt autoremove.

Run sudo purge_old_kernels, command from byoby package if still remains any old kernel version (in addition to the current and previous version which are always kept as a safety precaution).
