This shouldn't matter for solving this bug.  I believe the only thing you
need is, at line 83 when checking the secureboot_key values:

                        if [ -z "$key" ] && [ -z "$again" ] && \
                           ! db_fget shim/${action}_secureboot seen && \
                           ! db_fget shim/secureboot_key seen
                        then
                            echo 'no key given in non-interactive mode; doing nothing'
                            exit 0
                        fi

Title:
  update-secure-boot-policy behaving badly with unattended-upgrades

Status in shim-signed package in Ubuntu:
  Incomplete
Status in unattended-upgrades package in Ubuntu:
  Invalid

Bug description:
  Currently, unattended-upgrades will automatically install all updates
  for those running development releases of Ubuntu (LP: #1649709)

  Today, my computer was acting very sluggish. Looking at my process
  list, I saw/ usr/sbin/update-secureboot-policy was using a log of CPU.

  I killed the process. I have a /var/crash/shim-signed.0.crash but
  since it's 750 MB, I didn't bother submitting it or looking at it
  more. Maybe it crashed because I killed the process. Also, I see that
  unattended-upgrades-dpkg.log is 722 MB.

  Today's update included both VirtualBox and the linux kernel.

  I am attaching an excerpt of /var/log/unattended-upgrades/unattended-
  upgrades-dpkg.log

  This message was repeated a very large number of times (but I only
  included it once in the attachment:

  "Invalid password

  The Secure Boot key you've entered is not valid. The password used must be 
  between 8 and 16 characters."
