Package helpers

Introduction

This set of scripts are helpers that modify and create the source packages coming from the Ubuntu upstream which need it. It might be because they contain non-free stuff, references to Ubuntu that need to be changed, or because we want the package to work our way.

This helpers are similar to some of those in the gNewSense builder, we took some ideas and even some lines from them. If you plan to build an Ubuntu derivative of your own, we suggest you to use Builder instead of this helpers.

Once a new package is added, it takes priority over the original one from Ubuntu, so they never enter into the repo from upstream and need to be compiled with this helpers and pushed into reprepro.

To add a package to the list, follow the CONTRIBUTING guidelines. Steps

Those are the steps done by the helpers:

• Create local apt configuration, so you don't need to be root to run the helpers.
• Get the ubuntu and trisquel gpg keys.
• Get the source packages from their original repo.
• Uncompress them.
• Apply the changes described in the helper.
• Re-package it, adding "triquel$VERSION" version string.

Recommendations

You don't need to use sudo in order to run those scripts, but some extra packages are needed:

sudo apt-get install dpkg-dev sed git gnupg-curl rpl devscripts quilt patch cdbs

Take care to use the right sourcePackageName, many source packages produce several binary packages.

apt-cache showsrc binary-package 

Can help you.

If possible, use sed to replace chains in the upstream source without the need of external files or patches. If you really need to include a file, place it at the DATA/sourcePackageName directory

Do not replace all references to Ubuntu in the package, just those that would actually be shown to the user. Avoid replacing copyright statements!

Try to write your replacements in a way they might work in future versions of the upstream package. Well written regexps and sed will help with that.

You can test your changes by doing them inside the PACKAGES/sourcePackageName/source/ directory, and running

dpkg-source -b 

before being added to the helper script

Netinstall

Included are the set of scipts used to generate the network installer images found in Trisquel GNU/Linux LTS (version 2.0, 4.0, 6.0... and up). The scripts may not be available for all versions.

To generate the images, we run the following scripts:

make-apt-setup

make-base-installer

make-choose-mirror

make-main-menu

make-netcfg

make-net-retriever

make-pkgsel

Then we push the results into the Trisquel repository and run the script make-debian-installer to build the final images.
