I've been very stupid and while trying to free space on /boot, I think I've accidentally deleted my current kernel.
How it happened:
>>uname -i
linux-image-extra-4.4.0-24-generic
now uname -i only gives:
x86_64
I already tried freeing more space on boot: sudo apt-get autoclean sudo apt-get clean sudo apt-get autoremove
Still has 0 space available.
ls -l \boot gives:

I don't really understand why my /boot is still full. There are no linux headers in there anymore. Are they cached somewhere?
Any help is greatly appreciated. I don't have a cd drive or something here, so hopefully I can solve this fairly simple...
Otherwise, this might be time for a fresh install. Obviously I am currently backing up my hard drive...
