Hey All,
   Has anyone done a release upgrade from wily to xenial recently (like since the gdm3 migration landed?).

If so did you get a debconf question asking to choose display manager? In theory you shouldnt since the migration scripts reset things from gdm
-> gdm3 (so long as gdm was the default before upgrade). I did hit it on upgrading my laptop but not 100% if it was set to gdm or lightdm at the
time.

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
  Version table:
 *** 1:15.10.3 0
        500 http://za.archive.ubuntu.com/ubuntu/ wily/main amd64 Packages
        100 /var/lib/dpkg/status


Thanks

All the best,

Bruce
