dpkg: error processing package shim-signed (--configure):
 subprocess installed post-installation script returned error exit status 1

This indicates that the package manager frontend was shut down while
package configuration was still in progress.  You must have a valid
package manager frontend in order to correctly configure the UEFI Secure
Boot bootloader for use with dkms modules.

To correct this issue, you will want to run 'sudo dpkg --configure -a'
from a terminal.
