Title:
  Ubuntu 18.04 boot extremely slow

Status in plymouth package in Ubuntu:
  Confirmed

Bug description:
  I have upgraded Ubuntu 16.04 (amd64) using Gnome as desktop to Ubuntu
  18.04. Ubuntu 16.04 took just over 20 seconds from the time a
  selection on the Grub boot menu was made until the login screen was
  displayed. On Ubuntu 18.04 it takes about 20 seconds (from Grub menu)
  to display the boot splash screen and in total it takes about 2min
  30sec until the login menu (gdm) is displayed.

  Expected behaviour: 
  I would expect a new LTS release to have a similar boot time than the previous release. At this time I am experiencing boot times slower that those I had a few years ago from a traditional hard drive (which used to be just under 2min)

  Additional information:
  I have recently built two Ubuntu servers (17.10 in expectation of upgrading to 18.04 upon release). I found that the boot process went fairly smooth right until the end where it seems to wait for about a minute for what seems to be a network connection. After that wait period the text login prompt is displayed. So I am guessing that there might be a service start timeout which blocks the process.

  $ lsb_release -a
