E: Sub-process /usr/bin/dpkg returned an error code (1)

I was getting this error message while I was trying to upgrade the kernel on my VPS:
/usr/sbin/grub-probe: error: cannot find a device for / (is /dev mounted?).
run-parts: /etc/kernel/postrm.d/zz-update-grub exited with return code 1
Failed to process /etc/kernel/postrm.d at /var/lib/dpkg/info/linux-image-3.8.0-34-generic.postrm line 328.
dpkg: error processing linux-image-3.8.0-34-generic (--remove):
 subprocess installed post-removal script returned error exit status 1

You might not be able to upgrade the kernel on your VPS. Contact your VPS provider and get them to upgrade the kernel for you.
