I have read every thread I could find -- even the ones that say that the question has been answered elsewhere but none of them address the specific issue I am having. Update Manager ran and produced errors relating to unmet dependency and suggested using apt-get install -f which fails with this message:
Unpacking linux-headers-3.5.0-36 (from .../linux-headers-3.5.0-36_3.5.0-36.57~precise1_all.deb) ... dpkg: error processing /var/cache/apt/archives/linux-headers-3.5.0-36_3.5.0-36.57~precise1_all.deb (--unpack): unable to create `/usr/src/linux-headers-3.5.0-36/arch/arm/mach-iop32x/include/mach/glantank.h.dpkg-new' (while processing `./usr/src/linux-headers-3.5.0-36/arch/arm/mach-iop32x/include/mach/glantank.h'): No space left on device
I suspect that the last 5 words No space left on device are significant but df and du both show adequate space. So I am wondering, what device needs more space?
