Title:
  Unable to boot in UEFI+secure boot mode

Status in cd-boot-images-amd64 package in Ubuntu:
  Fix Released

Bug description:
  The problem:

  Trying to install the QA daily build for Kubuntu Groovy 20200824 -
  when booting from the USB boot media I receive the following error:

  Error

  Verification failed: 
  (0x1A) security violation 

  Followed by an OK box - which when selected offers to import the SHIM
  key

  This error occurred on 2 machines running in UEFI+secure boot mode:

  1: Dell [Inspiron] 3521, (i3-3217U, 4GB, Intel HD Graphics 4000, Intel
  HM76 chipset 10/100 Mbps ethernet controller integrated on system
  board, WiFi 802.11 b/g/N, Bluetooth 4.0, 500 GB hd)

  2: Acer [Aspire] E3-111-P60S (Pent.N3530, 4GB, Intel HD Graphics,
  Realtek  RTL8111/81681/8411 GB Ethernet, Qualcomm Atheros AR9462
  Wireless, Bluetooth Atheros A315-53, 500 GB hd)

  Disabling secure boot the machines then boot normally in UEFI mode

  Will test further some of the other flavors..
