Title:
  sleep mode doesn't work on encrypted Ubuntu 21.04 anymore. The
  computer does not wake up from sleep mode.

Status in ubuntu-release-upgrader package in Ubuntu:
  Confirmed

Bug description:
  1) Description:	Ubuntu 21.04
  Release:	21.04
  2) not applicable
  3) I expect the computer to wake up from sleep mode after pressing the power button as it did before the release upgrade
  4) The computer screen remains black and the only way to restart the computer is to hold the power button for long, to turn it off and then to turn it on again. Unsafed work is then of course lost.

  I also tried telling the computer to not go to sleep mode, but after
  not using it for some time, the screen was black anyway and it wasn't
  possible to use it unless by forcing a restart.
