Title:
  plymouth hook hangs waiting for input

Status in The Ubuntu-power-systems project:
  New
Status in plymouth package in Ubuntu:
  Confirmed

Bug description:
  In the fix for LP: #1864586 the following change was made:

   THEME_PATH="$(update-alternatives --query default.plymouth 2>/dev/null | sed -e '/^Value:/!d' -e 's/^Value: \(.*\)/\1/')"
  +IMAGE_PATH=$(grep "ImageDir *= *" ${THEME_PATH} | sed 's/ImageDir *= *//')
   THEME="$(basename ${THEME_PATH:-none} .plymouth || true)"
   THEMES="/usr/share/plymouth/themes"

  Unfortunately, if the default.plymouth alternative is not set (as is
  the case in the Raspberry Pi images for instance), then THEME_PATH
  winds up blank. The introduced IMAGE_PATH line then hangs waiting for
  input (as grep isn't given a filename to read).

  I ran into this during an "apt upgrade" (which called update-
  initramfs, and thus the plymouth hook) on a focal pi image; worked
  around it by hitting Ctrl+D to let it continue, which allowed
  everything to proceed as normal.
