Ubuntu PPA's in Debian

How to use Ubuntu PPA's in Debian

Ubuntu is the most popular Linux distribution in the world. As a result, it enjoy's more third party support than most other distributions, including Ubuntu's parent, Debian.

Ubuntu packages don't always work on Debian. Actually, more often than not, there's some kind of problem running or installing them. Plus, Debian isn't really set up to interact with Ubuntu PPAs.

Install the Dependencies

Before you start, there are a couple of general build dependencies that you'll need. Of course, you need the general build tools, plus some Debian packaging scripts.

# apt install build-essential devscripts

That's really all! You might need some specific dependencies for the package that you want, but that'll be later.

Add the Source PPA

Next, you'll need to find a PPA that you want to use. Most Ubuntu PPAs have a section where you can view the actual deb and deb-src records. On Launchpad, it's under a menu labeled "Technical details about this PPA." You'll need to copy the deb-src record.

Open up your text editor of choice as root, and create a .list file under /etc/apt/sources.list.d/ for your new PPA. Select the version of Ubuntu that is the closest match to your version of Debian.

Import The Key

You've got to import the signing key from the PPA in order for Apt to update your repositories and install. It's usually displayed prominently on the PPA homepage. Copy the key following the /. Then, run the following linux command using your copied key.

# apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys THE_KEY

After Apt imports the key, run an update.

# apt update

Build

You can actually build your new packages as a regular user. Actually, it's better to do it that way. Create a directory where you want to build your packages, then cd into that directory. Once inside that directory, run the following linux command to build your packages. Substitute the name of the package that you want to build and the version of Ubuntu your PPA is from.

$ apt source -t artful --build packagename

This will take some time, depending on the package. This is the place where you may encounter dependency errors. There are a few ways to solve them. You can manually copy the list provided by the script, and install them. If the package is a variation of an existing Debian package, you can use apt build-dep. Unfortunately, that won't work with your PPA. Apt only allows build-dep from the default repository.

Install With DPKG

Once you have your packages, you can install them as root using dpkg. It does take wildcards, so as long as there aren't any other Debian packages in your build directory, you can do something like this:

dpkg -i *.deb

Unless there is some strange unforeseen conflict(There shouldn't be, since you built them), your new packages will install on Debian.

Or you can directly install packages as you do in Ubuntu

sudo apt-get install package_name

This might not work on every package

This won't work in every situation, but it will work in most. If the source isn't available, you won't be able to build the packages. You can certainly try installing the existing binaries, but understand that it is a risk to do so.
