It is possible [4] for dependency hell to result from installing a prepared package via a package manager (e.g. APT), but this is unlikely since major package managers have matured and official repositories are well maintained. This is the case with current releases of Debian and major derivatives such as Ubuntu.
In several Linux operating systems, the Software Updater program updates installed software and their associated packages with important software updates for security or with recommended patches. It also informs users when updates are available, listing them in alphabetical order for users to choose which updates to install, if any.
Automatix allows the menu-driven installation of 56 different "capabilities", including commercial closed source programs such as the Flash plugin, Acrobat Reader, multimedia codecs (DivX, MP3, Windows Media Audio) and fonts, and programming compilers. Automatix was not recommended by the Ubuntu development team, which has criticised its ...
Ubuntu releases are also given code names, using an adjective and an animal with the same first letter – an alliteration, e.g., "Dapper Drake".With the exception of the first two releases, code names are in alphabetical order, and except for the first three releases, the first letters are sequential, allowing a quick determination of which release is newer.
A boot menu in Windows 7 showing options to start Ubuntu, which was added by the Wubi installer. Wubi adds an entry to the Windows boot menu which allows the user to run Linux. Ubuntu is installed within a file in the Windows file system (c:\ubuntu\disks\root.disk), as opposed to being installed within its own partition.
Advanced Package Tool (APT) is a free-software user interface that works with core libraries to handle the installation and removal of software on Debian and Debian-based Linux distributions. [4] APT simplifies the process of managing software on Unix-like computer systems by automating the retrieval, configuration and installation of software ...
Update managers also allow for security updates to be applied quickly and widely. Update managers of Linux such as Synaptic allow users to update all software installed on their machine. Applications like Synaptic use cryptographic checksums to verify source/local files before they are applied to ensure fidelity against malware.
An example of this difference would be the multiple versions of Ubuntu Linux vis-à-vis the single and constantly updated version of Arch Linux. A rolling release model should not be confused with a staged or "staggered" rollout, in which an update is gradually made available to an increasing percentage of users for testing or bandwidth reasons ...
