But what if I wanted to distribute my code to others via an apt repository? To do this, you can copy and paste the following commands into your terminal:. Debian, and Debian-based Linux distributions use. To start we will create a directory in the form:. This directory will be the root of the package. You can copy and paste the following to create one:. This package can then be installed using the -f option under apt-get install :. This concludes the first step of building a. If you have access to an existing apt repository, you could submit the deb to the repository maintainer, and call it a day.
In this step, we will show how to create your own apt repository which can be used to host one or more deb packages. Larger apt repositories create sub-directories for each program or project. If you want to support multiple architectures, make a directory above for each type e. Next, we will generate a Packages file, which will contain a list of all available packages in this repository. We will use the dpkg-scanpackages program to generate it, by running:.
Next we will create a Release file. Unfortunately dpkg-scanpackages does not create Release files. A list of all Packages files and their corresponding hashes and file size, for example:. How hard could it be? The APT package manager is free software that has handy features for Linux users, which supervises all the maintenance and grunt work. From installation and uninstallation to upgrading or removing the software on Ubuntu, Debian, and similar Linux distributions, it can help you do it all.
Making the most use of the software at your disposal, you can use it in the terminal connection SSH to make sure the data transferred between the host and the client is encrypted. You can use cron scheduling in the system administration scripts to notify administrators about the pending updates.
In addition to these advantages, there are many more benefits you get from the APT package manager. For instance, there are advanced installation functions and automotive configurations. With these, you can set up sources and apply them to other features and make the operations easier. Not only does the APT package manager solve the issues of installation and removal of the software, but it also keeps your repositories clean and presentable.
All the packages and software data will be stratified. Once the APT package manager is used, upgrading your packages will become seamless. Every time there are installations, removals, or needed upgrades, the administrator will be informed.
Obsolete files will be removed automatically, and other subsequent operations will be executed sequentially. Since all the application software comes in packages and the packages need to be externally stored in a repository , the repo has to have the qualities to be a good host to all the essential packages.
Thus, you need to make sure the packages are handled optimally by a unified and developer-friendly interface. This is true for packagecloud, which offers these functions and more services as well. NOTE: To install and manage packages, previously you had to use the apt-get command, while the apt-cache command had to be used for exploring packages on Ubuntu and Debian. However, the apt command has since been introduced to consolidate both apt-get and apt-cache commands to make use of the above user-friendly and uncomplicated.
Now, Debian and Ubuntu suggest you use the apt command where possible. Thus, consecutively in this guide, we will make use of the apt command where possible. To install multiple packages, specify the following command:. To install the package with APT, you do not have to write down a complete name. You can just add a phrase or a portion of the file name. For instance, if you want to install Nmap, you can write Nmap for the package name without the package version number.
It is unlikely that you will experience any failures during install due to missing dependencies. This is also a strength of APT. NOTE : The remove commands swipe out the package binaries but keep the data files and package configurations. If I generally use Ubuntu trusty package sources, then temporarily add utopic to my sources.
It won't tell you where the currently installed version came from. It can be different, e. Show 3 more comments. Basic commands from apt --help Other also easy to remember subcommands: apt list — list packages based on package names apt search — search in package descriptions apt show — show package details apt update — update list of available packages apt install — install packages apt remove — remove packages apt purge — remove packages and configuration files : Removing a package removes all packaged data, but leaves usually small modified user configuration files behind, in case the remove was an accident.
