How can we increase the severity/importance here to get attention? When this happens, usually we can get out of it, but I ran into this annoying situation of conflicting packages. I couldn't do the usual https://ubuntugenius.wordpress.com/2011/01/08/ubuntu-cleanup-how-to-remove-all-unused-linux-kernel-headers-images-and-modules/, because:

Title:
linux-headers will eat your inodes on LTS.
Status in update-manager package in Ubuntu:
Confirmed
Bug description:
Hello all,
Summary
-----------------
Both linux-image-* and linux-headers-* are installed every time you upgrade the kernel. However, they are never removed by any maintenance process.
Every linux-headers-*-generic-pae package has approx. 6,700 files on
it. Regular headers packages have even more files: around 11,700 files
each.
Although these packages' files won't occupy much space, after some
years (think LTS installation), they will "eat" all the inodes on your
root partition.
The first effect you'll encounter will be the you are unable to
upgrade your system.
This is a situation that will affect all users, however it will be a
greater problem regular non-technical user.
There's no simple, high-level tool to solve this problem.
Case Study
---------------
I have a 2-year-and-8-months old 10.04 installation. I have a ~10GB root partition, which is double of the minimum recommend (5GB).
$ df -h --type=ext4
Filesystem Size Used Avail Use% Mounted on
/dev/sda5 9.4G 6.2G 2.8G 70% /
/dev/sda6 94G 45G 45G 51% /home
It looks that I had plenty of space left to upgrade, but I got this
error while upgrading:
unable to create `/usr/src/linux-headers-2.6.32-45/arch/s390/include/asm/nmi.h.dpkg-new'
(while processing `./usr/src/linux-headers-2.6.32-45/arch/s390/include/asm/nmi.h'): No space left on device
It was because of I was running out of inodes:
$ df -i /
Filesystem Inodes IUsed IFree IUse% Mounted on
/dev/sda5 625856 618015 7841 99% /
Why? Because the huge amount of linux-headers files:
$ find /usr/src -type f | wc -l
355112
That is more than three hundred and fifty thousand files!
These are the packages that I removed:
