My machine has got into a state where I cannot apt-get anything.
When I run apt-get upgrade I get

You might want to run ‘apt-get -f install’ to correct these.
The following packages have unmet dependencies.
linux-headers-generic-lts-xenial : Depends: linux-headers-4.4.0-124-generic but it is not installed
E: Unmet dependencies. Try using -f.
So I do apt-get -f install:

Indicates the disk is full. It has about 3GB and 3.7k inodes free so I don't know if I believe that's really the problem:

I have freed up a load of space already, but it has not helped. A huge amount of the space and inodes are used by old linux-headers, linux-image and linux-image-extra packages which never get deleted. /usr/share contains 4.3GB / 960,871 files pertaining to linux-headers, for example.
apt-get autoremove and apt-get autoremove -f both fail in similar ways. I am stuck being told to free up space, but the thing using up the space doesn't work because (it says) there is no space, even though there is.
How can I get out of this cycle please?
In such cases I tend to just manually delete some old kernel headers in /usr/src/. In my experience this does not lead to errors when removing the header package later on.
On my machine headers of one kernel are more than 10k files, so 3.7k free inodes don't get you far when installing kernel headers. The low amount of free inodes is definitely a problem on your machine and can often be solved by apt-get autoremove to remove old kernels and their headers.
