I don't know how to read systemd-analyze well enough to understand how to fix my own delayed boot problem. Ubuntu 17.10 booted very quickly for me, and I understand that 18.04 is actually faster once configured correctly.

Can you help identify the delaying process(es) and any solutions?

Try this

systemctl stop NetworkManager-wait-online.service
systemctl disable NetworkManager-wait-online.service

This service does not come from out-of-box Ubuntu 18.04
I tcan be installed as dependence, im told that Steam installs it

  • Odd. I don't have Steam! I disabled and rebooted. Startup finished in 4.711s (firmware) + 3.238s (loader) + 35.111s (kernel) + 9.057s (userspace) = 52.118s Same results. – PANDA Stack Jun 04 '18 at 03:34
  • apt-daily-upgrade.service can be disabled too – cmak.fr Jun 04 '18 at 06:27
  • This fixed the issue: https://askubuntu.com/questions/1013830/slow-boot-long-kernel-load-time-due-to-wrong-resume-device. However, I am having strange graphical switches between boot, login screen, and logged in desktop. Working on drivers now. – PANDA Stack Jun 04 '18 at 14:27
