Not authorized to run synaptic

[Bruno Schneider <boschneider@gmail.com>]

Hi all,

I'm running Debian Testing, using XFCE. I run synaptic package manager
from a launcher I made a few years ago. After a system upgrade today,
I can no longer run synaptic from the launcher.

Using the command line (same command as the launcher), I got this:

    $ /usr/bin/synaptic-pkexec
    Error executing command as another user: Not authorized
    This incident has been reported.

If I use sudo, then it works, but pkexec used to open a graphical
password input to run synaptic as root, which is what I want, for
opening it using the launcher. What did I break?
