APT is a tool that functions as an automated general software installer for Linux systems; all one has to do is tell it what software package they would like to install, and the program will automatically fetch the software and all of its dependencies (other packages that a program relies on, such as a library for processing ZIP archives) from a central ''repository''. It will also automatically handle upgrades by automatically checking if the repository version of a package is higher than the currently installed version, and it can even handle the use of multiple repositories and linking between them; for example, if a piece of software is deemed worthy of inclusion in Debian's main repository, but as a stable release, the software developers can provide their own repository to provide a more experimental version for users who want it, and once that repository is added to APT's source list, APT will automatically realize that it should use the experimental version, since it has a higher version than that of the main repository. Although this wasn't the first package management system for easy Linux installation (that honor goes to {{w|RPM Package Manager|RPM}}), it is the first one that seamlessly integrated online installation and upgrades into the mix. |

It's what you might call the "canon" of Debian, containing only those packages that have been approved by official Debian developers. Thus, getting a package on debian-main means that it, theoretically, conforms to a standard of quality. |

In some parts of the world they are also considered a delicacy. [[Cueball]] probably does not appreciate this as they crawl over his body searching for food, apparently spontaneously generated by APT as it saw that it needed "locusts" to install the package. |
The title text is an error line from <code>dpkg</code>, the program used to install/remove APT packages. Every package contains several scripts (although some of them may be empty) that are run on various events related to that package; these are used to perform any setup/cleanup tasks the package needs. This line is an error line indicating that one of those scripts has failed.

The exact value has no real significance other than signifying to a user or other application that understands what the code means; neither <code>dpkg</code> nor the Linux kernel itself treat any exit value specially, apart from checking whether the value is 0 (which means no error). | + | * <code>returned error exit 163</code>: "Returned error" means just what it says, the script returned an error.
