Here we take the example of the package mame, from which we want to install a newer release availaible in sid/experimental. If the package you're looking for not available in Sid, but in a Ubuntu PPA, you can have a look at CreatePackageFromPPA.
We don't need to be root here except the first and last steps.
- Install Debian SDK
- Find which version is available in the debian archive
- Download the .dsc file from the sid release
- Find and Install missing build dependencies as found in debian/control
- Indicate in the changelog a backport revision number
- Test if we can successfully build the package
- Build a package properly , without GPG signing the package
- Install and enjoy !
- Go further
Install Debian SDK
su -c "apt-get install devscripts build-essential debian-keyring"
Find which version is available in the debian archive
rmadison mame --architecture amd64 mame | 0.146-5 | wheezy/non-free | amd64 mame | 0.146-5 | jessie/non-free | amd64 mame | 0.146-5 | sid/non-free | amd64 mame | 0.148-1 | experimental/non-free | amd64
Download the .dsc file from the sid release
From your web browser at http://packages.debian.org/sid/mame, look at the dsc file and copy the link location
dget -x http://ftp.de.debian.org/debian/pool/non-free/m/mame/mame_0.148-1.dsc
Find and Install missing build dependencies as found in debian/control
cd mame-0.148 dpkg-checkbuilddeps su -c "libexpat1-dev libflac-dev libgconf2-dev libgtk2.0-dev libjpeg8-dev libportmidi-dev libsdl-ttf2.0-dev libsdl1.2-dev zlib1g-dev"
Indicate in the changelog a backport revision number
dch --local ~bpo70+ --distribution wheezy-backports "Rebuild for wheezy-backports."
This will add something like ~bpo70+ to the package version number. The tilde ~ makes the package inferior in version, which should allow a proper package upgrade when you upgrade to the next debian release (ie your package will be replaced with the official debian package)
Test if we can successfully build the package
fakeroot debian/rules binary
Build a package properly , without GPG signing the package
dpkg-buildpackage -us -uc
Install and enjoy !
su -c "dpkg -i ../mame_0.148-1_amd64.deb"
