I've got several Ubuntu 10.10 servers which should all be set to do automatic security updates.
Is there any way I could get them to send me an email when they apply updates (particularly if they fail)?
I'm using r-u-on to monitor availability, disk space etc but the security updates are very important and I don't have a good way to monitor them.
I could possibly script something myself but I figured it's the kind of thing that's probably been solved many times already.
It turns out that the unattended-upgrades package actually has a parameter for this:
EDIT: in fact there is more than one way to do it, and it's documented in the server manual: https://help.ubuntu.com/10.10/serverguide/C/automatic-updates.html
