After visiting How do I list the default installed packages?, I read ubuntu-14.04.2-desktop-i386.manifest and found (Ctrl+F) that it lists gparted 0.18.0-1 but (we know that) gparted is not installed by default!

However, Gparted is installed when try Ubuntu (using Live CD Environment) hence seems to be removed while installing system.

So, I want to know Why package listed in .manifest is not installed with OS?

  • It is uninstalled at the end of the installation. If you look at the messages, it will list GParted, a number of i18n/l10n packages and a few others. – muru Jun 15 '15 at 11:15
  • `apt-cache show gparted` tells me : `Task: ubuntu-live, ubuntu-usb-live, edubuntu-live, edubuntu-usb-live, xubuntu-live, lubuntu-live, ubuntustudio-desktop, ubuntu-gnome-live` . So perhaps the installer checks that somehow ? – Sergiy Kolodyazhnyy Jun 15 '15 at 11:17
  • @muru btw, what is `i18n/l10n`? – Pandya Jun 15 '15 at 11:20
  • [Internationalization and localization](https://en.wikipedia.org/wiki/Internationalization_and_localization) - essentially getting software to support multiple natural languages. Once the user picks a language for installation, the installer removes the others. – muru Jun 15 '15 at 11:21

The manifest says what's on the CD. Some things are removed after the install but I haven't found a reliable way to work out what they are short of downloading the ISO.

if you have the ISO in front of you, compare /casper/filesystem.manifest and /casper/filesystem-remove.manifest.

It's that second file that contains packages that are on the CD that are removed after installation, unless they have other dependencies — which some of those things do.
