Slow boot time on fresh minimal install of 18.04

Question

I'm running Ubuntu 18.04 minimal fresh install with dual boot Windows 10 on a Samsung 850 EVO SSD.

$ systemd-analyze time              
Startup finished in 17.129s (firmware) + 3.573s (loader) + 3.058s (kernel) + 22.988s (userspace) = 46.750s
graphical.target reached after 22.981s in userspace

$ systemd-analyze blame | head -n 10
         20.674s plymouth-quit-wait.service
          5.077s bolt.service
          3.252s NetworkManager-wait-online.service
          1.483s docker.service
           863ms dev-sda4.device
           820ms snap-gnome\x2dlogs-31.mount
           787ms fwupd.service
           742ms systemd-resolved.service
           690ms snap-gnome\x2dsystem\x2dmonitor-39.mount
           546ms dev-loop2.device

Any ideas why boot time takes so long? Even my Windows 10 partition boots up faster.

As answered in this similar question, it may be possible to workaround/resolve this issue by passing the noresume option to the kernel.

To update GRUB so that it passes this option to the kernel automatically on boot:

1. edit the /etc/default/grub file so that the string noresume is included in the GRUB_CMDLINE_LINUX_DEFAULT variable:

   GRUB_CMDLINE_LINUX_DEFAULT="quiet splash noresume"

2. run this command to update grub: sudo update-grub

3. reboot the computer
