Title:
  Ubuntu minimal install takes longer than normal install when
  installing from official ISO

Status in ubiquity package in Ubuntu:
  Confirmed

Bug description:
  Expected installation: Minimal installation should not take longer
  than normal installation.

  Performed a test of Ubuntu 19.10 installation with Erase Disk option
  on both a 5400rpm hard disk and a SATA 3 SSD when they are connected
  directly to a SATA 3 interface and internet speed and mirrors are
  fast. When installing on a 5400rpm hard disk, minimal installation
  takes almost an hour but normal installation takes about 30 minutes.
  When installing on a SATA 3 SSD, minimal installation takes about 10
  minutes while the normal installation takes about 5 minutes.

  Why the opposite of the expected installation occurs is because the
  Minimal installation mode seems to 'debloat' the normal installation
  by removing packages that are not required which include games, media
  players and other applications, locales and many of them are not of
  the selected language and installer related packages.

  I request a fix to the ubiquity installer such that only the required
  packages are installed based on language and other options especially
  whether Minimal or Normal set before the start of installation on
  hardware. This will save a lot of time, especially on mechanical hard
  drives.
