It also comes with security benefits because applications are more isolated from each other and from core parts of the OS than they normally would be.īut snaps-initially created for Ubuntu phones and then Internet of Things devices-could only be installed on Ubuntu. This allows users to update and roll back applications without causing problems to the rest of their operating system. 'With snap packages, applications are installed in their own container, and all the third-party applications are installed with them so there are no version conflicts.' 'Snap packages solve this problem by creating self-contained packages,' we noted in our review of Ubuntu 16.04, which brought snaps to servers and desktops. Applications often require a lot of dependencies, making things more complicated, for example, when one application needs one version of another piece of software and a second application needs a different version of that other piece of software.įurther Reading Why Ubuntu’s creator still invests his fortune in an unprofitable company These packages consist of the application a user wants to install, and they can also install other things that the package depends on in order to run (libraries, other applications, scripting, support files, and so on). Traditionally, applications for Ubuntu and similar distributions are packaged in the deb (short for Debian) format. If you have no idea what the above paragraph means, here's a summary. Canonical today is announcing that snapd, the tool that allows snap packages to be installed on Ubuntu, has been ported to other Linux distributions including Debian, Arch, Fedora, and Gentoo, among others. The latter is an empty package that has its 'ca' counterpart as a dependency.Ubuntu's 'snappy' new way of packaging applications is no longer exclusive to Ubuntu. Headless Java Runtime Environment (without GUI support).įor each package listed in the table there is another package available without the -ca- suffix in its name.įor example, zulu11-ca-jdk and zulu11-jdk. Java Runtime Environment including graphic components. Headless Java Development Kit (without GUI support). Java Development Kit (including graphic components). The placeholder stands for the major Java version. The following table lists the DEB packages that are available from the Azul APT repository. You can also install the dependent packages separately.įor example, if your application requires JRE only, you can install just the JRE package (or headless JRE) without downloading unnecessary dependencies.

When you install the JDK package, you install the package itself and all its dependencies.

Thus, the JDK package is split into multiple packages, such as JRE, documentation, source files, and so on. The Azul APT repository uses the package dependency paradigm typical for Linux distributions where packages that provide complex functionality depend on packages with more basic functionality.
