Hi Tim,

I thought I would try this out, but update-manager is aborting with the 
following:
octoquad@ugqa:~$ update-manager -d
**
Gtk:ERROR:/build/gtk+3.0-QN_dK1/gtk+3.0-3.16.7/./gtk/gtkprogressbar.c:609:tick_cb: 
assertion failed: (priv->pulse2 > priv->pulse1)
Aborted

I can't get a gdb backtrace due to ""/usr/bin/update-manager": not in 
executable format: File format not recognized" and using strace the 
application works fine.
Sometimes it will work ok with update-manager -d but will output:
"WARNING:root:file 'xenial.tar.gz.gpg' missing" with a dialog box saying 
"Failed to fetch
Fetching the upgrade failed. There may be a network problem."

Even though internet connectivity is working correctly.

I'll try again tomorrow, perhaps this is just a temporary problem with 
downloading, but not sure if I should file a bug report regarding the 
app aborting.
Any ideas on how I can get a decent backtrace? The crash is 
"update-manager crashed with SIGABRT in g_assertion_message()" which I 
don't think is very useful.
update-manager:
  Installed: 1:15.10.3
  Candidate: 1:15.10.3

Thanks
