Please keep in mind that this is meant as a quick howto for how to build private backports and is not the way we expect from official backports for backports.debian.org. For official backports, see this article.
Here we take the example of the package coreutils, 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.
Another method for backporting a sid package to testing or stable is described in this section of the Debian Unstable page in the Wiki.
Contents
- Install Debian packaging tools
- Find out which version is available in the Debian archive
- Download the .dsc file from the sid release
- Install build dependencies
- 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 packaging tools
sudo apt-get install packaging-dev debian-keyring devscripts equivs
Find out which version is available in the Debian archive
$ rmadison coreutils --architecture amd64 coreutils | 8.23-4 | oldstable | amd64 coreutils | 8.26-3 | stable | amd64 coreutils | 8.30-3 | testing | amd64 coreutils | 8.30-3 | unstable | amd64
Download the .dsc file from the sid release
From your Web browser at http://packages.debian.org/sid/coreutils, look at the .dsc file and copy the link location
dget -x http://deb.debian.org/debian/pool/main/c/coreutils/coreutils_8.30-3.dsc
Note: If the above command complains about your ~/.gnupg directory not being found, run gpg -k to initialize the GnuPG directory before retrying.
Or, alternatively, add sid to your sources.list, run apt update, download the source using the command below,
apt source -t sid coreutils
Install build dependencies
cd coreutils-*/ sudo mk-build-deps --install
This will install a package named coreutils-build-deps depending on the listed build dependencies. If you remove this package later, the actual build dependencies will be marked as "automatically installed and no longer needed" and can be cleared with apt autoremove.
Indicate in the changelog a backport revision number
dch --bpo
This will add something like ~bpo9+ 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 (i.e. your package will be replaced with the official Debian package).
Test if we can successfully build the package
fakeroot debian/rules binary
If this should fail with a missing file, apt-file may be useful in locating the dependency you require.
Build a package properly , without GPG signing the package
dpkg-buildpackage -us -uc
Install and enjoy!
sudo apt install ../coreutils_*_*.deb
