Comment 4 for bug 1568368

This bug was fixed in the package update-manager - 1:17.04.2

---------------
update-manager (1:17.04.2) zesty; urgency=medium

  [ Jeremy Bicha ]
  * Update alternate dependencies for policykit-1-gnome:
    - Add virtual polkit-1-auth-agent
    - Replace non-existant policykit-1-kde with polkit-kde-agent-1
    - Replace razorqt-policykit-agent with lxqt-policykit
      (since lxqt is the replacement for razorqt)

  [ Manzur Mukhitdinov ]
  * UpdateManager/Core/MetaRelease.py:
    - Add a clearer error message when a network failure occurs

  [ Brian Murray ]
  * UpdateManager/Dialogs.py:
    - Remove misleading ellipsis in “Restart Now” action button. Thanks to
      Adolfo Jayme for the change. (LP: #1568368)

  [ Steve Langasek ]
  * Drop estimate_kernel_size_in_boot() from UpdateManager/Core/utils.py; this
    was only used in ubuntu-release-upgrader so the code has now moved there
    (with code fixes). Ensure upgrade ordering with Breaks: on older
    python3-distupgrade. LP: #1646222.
