I have some kind of internet that I don't really recommend to anyone, but there -- it's a limiter traffic (4G from a mobile carrier). Fortunately, in a way, the night traffic is free, so I am looking for a way for my computers to automatically download and install updates. I think unattended-upgrades should be the way, however I'm not 100% sure if it supports this.
So, would there be a way to make it run only at 2 AM, for example? Or, if not, is there an alternative?
