[Bug 1259326] Re: system-update panel not blocking screen lock/blank while downloading

[Barry Warsaw]

I'm also not sure this will directly address the original description,
since AFAICT, the powerd API only gives me the option of preventing
suspends.  We have no control over display locking and blanking.

I'm also not clear on how blanking or locking would have any effect on
system-image-dbus downloading files, unless this causes system-settings
to call PauseDownload and never resume it?

Another thought: should system-settings be calling the powerd API
instead of system-image-dbus?

Title:
  system-update panel not blocking screen lock/blank while downloading

Status in Ubuntu system image (server/client/updater):
  Confirmed
Status in “system-image” package in Ubuntu:
  Confirmed
Status in “ubuntu-system-settings” package in Ubuntu:
  New

Bug description:
  The system-update panel is not blocking the screen form
  locking/blanking, while a download of a new image is in progress.
  Sometimes this seems to result in the new image not being fully
  downloaded (or the UI not properly representing the download, and
  assuming it hasn't been successful), leaving one with an "Install &
  Restart" button that immediately fails when pressed, with no way to
  retry the download.
