Title:
  Don't pull in network-online.target in apt-daily.timer

Status in apt package in Ubuntu:
  Fix Released
Status in apt source package in Xenial:
  Fix Released
Status in apt source package in Zesty:
  Fix Committed

Bug description:
  [Impact]
  apt-daily.timer is enabled on every boot and pulls in network-online.target via Wants and After. While nothing has an After=apt-daily.timer (or rather an After=timers.target) and this should thus not impact boot performance, the rc-local.service specifies an After=network-online.target and the login stuff (getty, gdm, etc) is ordered After=rc-local, thus severely increasing the time to login if nothing else pulls in network-online (like an LSB script).

  This works around the problem on most boots, the problem will only
  occur if the timer would have elapsed while the machine was off.

  [Test case]
  Well, the change is fairly obvious. Actually testing that is pointless, and depending on the system configuration, network-online.target might be pulled in by something else. So just look at the file and check that the network-online.target dependency moved to the service.

  [Regression potential]
  Literally none. We just move the dependency to the service which actually needs it.
