How to add Ubuntu official packages?

Greetings Chang-Yi Lee,

If these files already exist in the official Ubuntu repository, used in scope of ISO building - you may add these component names to the following file before building the new ISO:
https://github.com/stackforge/fuel-main/blob/master/requirements-deb.txt

There are other requirement files, for rpm, gems etc.

In your local repository this file is in
/fuel-main/requirements-deb.txt

If there is no required files in the default repositories - please add additional Ubuntu repositiory as following:
Run
`export EXTRA_DEB_REPOS="myrepo,http://url-to-your-repo"`
before running `make iso` or `make bootstrap`

Kind regards,
