I forgot to mention that I use SSD but it has not 4096 byte size
physical sector as mentioned somewhere above.

So for me the only reason for long boot time is UUID in file /etc
/initramfs-tools/conf.d/resume where I don't know why this was there.

Title:
  Lubuntu bionic boots slower than the other Ubuntu flavours with some
  SSDs

Status in initramfs-tools package in Ubuntu:
  Confirmed
Status in ubiquity package in Ubuntu:
  Fix Released

Bug description:
  See this thread at the Ubuntu Forums:

  https://ubuntuforums.org/showthread.php?t=2388799

  How come the ultra light Lubuntu Bionic needs 40 seconds from the grub
  menu to the log in screen, while the corresponding Kubuntu and Xubuntu
  Bionic can do it in 10 seconds in my Toshiba laptop?

  All the operating systems were installed from the Bionic Beta-2
  desktop 64-bit iso files and made up to date today (and reside in a
  new SSD connected via the internal SATA bay).

  -o-

  and to summarize the conclusion

  This supports the assumption, that there are problems for Lubuntu to
  manage SSDs with 4096 byte size physical sectors. But the other
  flavours of Ubuntu can manage it.

  Let us hope that this can help the Lubuntu developer to find and
  squash the bug.
