Thanks for your bug report and help to make ubuntu better. Journal logs will be helpful to know exactly what happens during your slow boot, do you mind pasting "journalctl -b" output here (and eventually boot in debug mode: add systemd.log_level=debug in grub to boot with it).
Please turn back the bug status to "new" once you have attached this, thanks!
