Public bug reported:
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.
