The APT protocol, or apturl, is a very simple way to install a software package from a web browser.
On computers where apturl is enabled, clicking on a special type of link on a web page starts the installation of one or several packages available in the package repositories of this computer.
For example, from a web page, when a Ubuntu user clicks on the link apt:packageexample , the apturl protocol will launch the package manager to propose the installation of the package called "packageexample" from the repositories available on the computer.
Please note that apturl is not aimed at replacing the current system of repositories and package manager. It is a complementary method.
To use this package installation method:
- you need to be on Ubuntu 7.10 or later
you need the package apturl to be installed (it is generally installed by default)
- you need a compatible web browser (see list below).
- apturl works by default with Firefox if it is installed from the Ubuntu repositories
- if you use a version of Firefox that you didn't install from the repositories, you need to enable the apturl in your browser, using the procedure below.
This mechanism applies to all recent browsers based on Firefox, such as Seamonkey, Swiftfox, IceWeasel, etc.

Use of apturl
In the Ubuntu Documentation, you will sometimes find sentences like for example:
Click on the name of the package ("supertux" in the example): if the apturl protocol is enabled on your computer, you will be proposed to install the package called "supertux".
Multiple packages can be linked to in documentation, they need only be separated by a comma. The following code is an example, first the source then the result.
[[InstallingSoftware#installing-a-package|install the following packages]]: '''''[[apt:rsync,xinetd|rsync xinetd]]'''''.
