[Launchpad Bug Tracker <1401425@xxxxxxxxxxxxxxxxxx>]

You have been subscribed to a public bug:

When Linux kernel is updated, a package with the new kernel version is
installed, and the system offers to reboot the machine (an icon appears
in the system tray). After reboot the new kernel is loaded, but the old
one is still installed. When I remove the old kernel packages (e.g.
linux-image-3.16.0-25-generic, linux-image-extra-3.16.0-25-generic,
linux-headers-3.16.0-25, linux-headers-3.16.0-25-generic) the system
offers to reboot again, even though that kernel is not used. In essence
this means that kernel upgrade requires two reboots.

Removing unused kernel packages should not require a reboot, and some
time ago it actually worked that way. I can't remember exactly which
kernel release broke that (probably, 3.16.0-24 or so).
