What can be a minimum install & upgrade

[Tazmman]

Hello. was hoping some could describe to me how to extract programs, to reduce the size of my OS. As well as pick the updates . thanks.

1. ??
2. Use the Ubuntu Minimal CD to create a system from CLI up.
3. Run

sudo apt-get --only-upgrade install package_name

to only upgrade (update) package_name.

I'm not completely sure I understood what you're asking. When you say "... extract programs, to reduce the size of my OS...", do you mean to remove them from your computer? If so, you can do it, but you have to be sure of what you are removing, because there is a real risk of data loss or making other programs or Ubuntu unusable when uninstalling and this might leave your system in a funky state, or you might select a critical system file for deletion and this leaves your system unusable.

But you can achieve it either by clicking Remove in the Ubuntu Software Center or at a terminal window, using the following command:

sudo apt-get remove --purge <package_name>

which will remove the package and it's config files.

Its better to build from the ground up instead of taking a full install and removing packages.

An example. To build a desktop using Unity you could install only the packages Unity depends on and not the recommended packages.

Like cortman said, use the mini iso and this command:

sudo apt-get install --no-install-recommends ubuntu-desktop

That basically turns the Unity 850MB install into a 150MB install.

And there are a 100 different ways to to a mini install, thats just one. Minimum GUIs are sometimes install on servers.

This can also be done with the mini iso.
