Over the next couple of Ubuntu releases, we're migrating from Synaptic
to Ubuntu Software Center and Update Manager. However, they currently
have this same problem as Synaptic.

Ubuntu Software Center uses aptdaemon for package installation, and
Update Manager from Maverick onwards will use aptdaemon too. So to fix
this problem in both programs, you could change aptdaemon so that any
package operation (1) inhibits session exit and (2) inhibits shutdown.

Here's the aptdaemon code:
https://code.launchpad.net/aptdaemon

Here's the reference for how to inhibit session exit:
http://people.gnome.org/~mccann/gnome-session/docs/gnome-session.html#org.gnome.SessionManager.Inhibit

Inhibiting shutdown can be done with an Upstart script. The
unattended-upgrades package contains a script doing the same thing:
https://code.launchpad.net/~ubuntu-branches/ubuntu/maverick/unattended-upgrades/maverick
http://upstart.ubuntu.com/getting-started.html

Thanks for getting involved!
