"restart required" dialog appears too frequently after being dismissed

[ash]

Whenever I run an upgrade that requires a reboot (e.g. kernel upgrade), I get a dialog saying "Please restart the computer to begin using your updated software" immediately after the upgrade; fair enough, I click "restart later". *Every time*, the same dialog appears about 3 minutes later, asking me to restart. Usually it goes away for a bit longer after I click "restart later" for the second time, but every time I do an apt operation it appears again.

I would suggest that, probably, three minutes is not likely to be enough time for _anyone_ to have finished doing whatever has caused them to press "restart later" – it's especially bad that the dialog reappears early if you do other things with apt, since you end up having to continually dismiss it if you're trying to fix something broken before you reboot.

Would it be an idea to rate-limit the dialog so that it appears, at most, once an hour or so?

Status changed to 'Confirmed' because the bug affects multiple users.

This also occurs for me, but the period seems more like 10 minutes after pressing "Restart later". Still, it is annoying.
