Title:
  Systemd taking long time to boot into desktop 18.04

Status in systemd package in Ubuntu:
  Confirmed

Bug description:
  ubuntu desktop 18.04 development branch with gnome/xorg @ 9/1/2018

  Systemd takes a long time to boot both from start to login and from
  login to desktop

  systemd-analyze blame showed apt daily services taking up to 1min and i disabled auto updates
  but it still takes a long time to boot to desktop, on a fast ssd

  here's the analyze log after apt.daily disabled:
