ubuntu-release-upgrader (1:18.04.21) bionic; urgency=medium

  * DistUpgradeQuirks.py: when a snap fails to install try the next one

    causes a Traceback. (LP: #1781412)
  * data/mirrors.cfg: Update the list of official mirrors.

  * Purge obsolete packages, if user agrees to remove obsolete
    packages. LP: #1775660
  * DistUpgradeQuirks.py, DistUpgradeController.py: move inhibiting of
    gnome-session idle so that it is called immediately after the upgrade
    starts (LP: #1778817), present a dialog notifying that the lock screen has
    been disabled (LP: #1174093), and do not reenable the lock screen as it
    may fail to work after a release upgrade. (LP: #1780342)
  * DistUpgradeQuirks.py: Add in a quirk for upgrading to Bionic that will
    check if the system has connectivity to the snap store and replace some
    desktop packages with snaps to ensure the system is similar to a fresh
    install. (LP: #1780841)
  * data/mirrors.cfg: Update the list of official mirrors.

Title:
  notify user that the lock screen has been disabled

Status in ubuntu-release-upgrader package in Ubuntu:
  Fix Released
Status in ubuntu-release-upgrader source package in Bionic:
  Fix Released

Bug description:
  [Impact]
  Users are not notified that their lock screen is disabled during an upgrade and may left there system in an insecure location during the upgrade process.

  [Test Case]
  1) Configure a screen lock with a short (2 minute?) timeout
  2) Upgrade from Ubuntu 16.04 to Ubuntu 18.04
  3) Observe that the screen is not locked during the upgrade process and you that you were not warned about it

  With the version of ubuntu-release-upgrader from -proposed you will
  receive a dialog telling you the lock screen has been disabled
  immediately before the upgrade begins.

  [Regression Potential]
  A new dialog is being added so there is little chance of regression.

  I set an upgrade running from 12.10 to 13.04 (my second attempt, the
  first had failed due to loss of network), and as I expected this to
  take some time, locked the screen and left.  I returned to an
  _unlocked_ screen, which is obviously a security risk.

  It was showing a debconf dialog (asking if I wanted to restart cron,
  atd, cups and rsync after upgrading libc6, probably not the most
  helpful thing to ask a user who may well have no idea what these are),
  but the logs suggest update-manager deliberately kills gnome-
  screensaver before starting the install phase (possibly a fix for bug
  319332 or similar problems?).

  If it is not practical to have screen lock actually working during an
  upgrade, I suggest either disabling it right at the start and giving
  an appropriate message if the user tries it, or pausing and waiting
  for user input if the screen is locked at the point where the lock
  needs to be disabled.
