full-upgrade (apt) and dist-upgrade (apt-get), in addition to performing the function of upgrade, also intelligently handles changing dependencies with new versions of packages; apt and apt-get have a "smart" conflict resolution system, and will attempt to upgrade the most important packages at the expense of less important ones if necessary.
Ubuntu is by far the most popular Linux distribution for running web servers; of the websites they analyse it is "used by 47.3% of all the websites who use Linux", [161] and Ubuntu alone powers more websites than Microsoft Windows, which powers 28.2% of all websites, or 39% of the share Unix has (which includes Linux and thus Ubuntu). All Linux ...

dpkg (Debian Package) itself is a low-level tool. APT (Advanced Package Tool), a higher-level tool, is more commonly used than dpkg as it can fetch packages from remote locations and deal with complex package relations, such as dependency resolution. Frontends for APT, like aptitude and synaptic , are used for their friendlier interfaces.
In Linux, if the script was executed by a regular user, the shell would attempt to execute the command rm -rf / as a regular user, and the command would fail. However, if the script was executed by the root user, then the command would likely succeed and the filesystem would be erased. It is recommended to use sudo on a per-command basis instead.
The Yellowdog Updater Modified (YUM) is a free and open-source command-line package-management utility for computers running the Linux operating system using the RPM Package Manager. [4] Though YUM has a command-line interface, several other tools provide graphical user interfaces to YUM functionality.
The Linux operating system is based on this kernel and deployed on both traditional computer systems such as personal computers and servers, usually in the form of Linux distributions (including Ubuntu and its derivatives), and on various embedded devices such as routers, wireless access points, PBXes, set-top boxes, FTA receivers, smart TVs ...
Inherited from the design of Nix, most of the content of the package manager is kept in a directory /gnu/store where only the Guix daemon has write-access. This is achieved via specialised bind mounts, where the Store as a file system is mounted read only, prohibiting interference even from the root user, while the Guix daemon remounts the Store as read/writable in its own private namespace.
