unsure; can't read Chinese errors; updater failing

[Mark Straka]

New install of Ubuntu Kylin (Chinese Traditional) 16.04. Updater and software downloads failing in spite of good Internet connection. Here is return from terminal:

~$ ubuntu-bug ubuntu-release-upgrader-core
/usr/share/apport/apport-gtk:16: PyGIWarning: Wnck was imported without specifying a version first. Use gi.require_version('Wnck', '3.0') before import to ensure that the right version gets loaded.
  from gi.repository import GLib, Wnck, GdkX11, Gdk

Here is the content of another error message window:
