There are at least twenty essential applications for any user Raspberry, as long as you are an end user who will use the equipment as a desktop computer. Nevertheless, if you are a developer and you will use this board for a specific projectthen that figure is considerably reduced.
If you did not know it, Raspberry has several ways to allow you to install applications on its system.regardless of the operating system you have installed.
For this reason, we show you this list of all the ways that you have access to place applications on the new plate that you have in your hand, as well you can do anything that comes to your mind.
Learn step by step how to install any program on a Raspberry Pi from scratch and without errors
There are four different ways that you can use to have the preferred applications. You can choose any of them, but We recommend you master 100% installations through the command consolesince it is the most frequent and effective.
Go for it:
with APT
The meaning of this acronym is Advanced Packaging Tool and it is a powerful manager that adds, update and remove apps onthe oldest distro that it has Linux. What Raspberry Pi OS is a system based on Debian, also has an ATP that fulfills these functions.
So you can make use of this official tool from the manufacturer:
- go to menu Debian and press the symbol “Commands”.
- will appear a command terminal in which you will write several lines of codedepending on the function you want to execute.
- To do an installation, type: sudo apt-get install package. Instead of (package) you put the name of the application.
- each application has a name that will define it in the command console.
- Then he APT asks for confirmation. You must type: sudo apt-get -y install package.
- Once the installation is finished, you should check the space that is available. To find out, write: df-h.
- If you wish update an appyou should type in the terminal: sudo apt-get update.
- Subsequently, write: sudo apt-get upgrade.
- Now if you want delete an appyou just have to enter: sudo apt-get remove package.
- Make sure that delete temporary filesyou do this with: sudo apt-get purge package and sudo apt-get remove –purge package.
With PiPackages
The PIPackages are the original packages created with python and that can also be installed on a Raspberry. Even, there is a significant developer community that prefers to use these programs.
Before starting to use them, it is important to have installed and updated a program that will allow compatibility with the Raspberry Pi:
- run the terminal command.
- sudo apt update, this updates the Raspberry PI OS, in case this is the installed operating system.
- sudo apt install python3-pip -y, this command allows the installation of pip.
- If you wish check versionyou can type this command: pip3 –version.
Once finished, to install applications, you must follow these steps, always from the Raspberry PI OS command terminal:
- pip3 install opencv-python, so installs the python opencv package.
Whenever there is an installation in this way, You will be able to see the progress of the process by means of a percentage. Upon reaching 100, there will be an alert message with the result of the installation.
With the source code of the program
The compilations are simplified when there is a program who manages the dependencies.
For that, we are going to install the Docker program, which creates a virtual container:
- docker run –rm hello-world, this is how the installation is done.
For this example, the source code for TensorFlow will be installed, which works as a form of machine learning and is open source:
- git clone https://github.com/tensorflow/tensorflow.git
- cd tensorflow
An update branch must be acquired, since by default the installation is done with the “master” branch, so you must type the following command:
- git checkout branch_name # r1.9, r1.10, etc
To start the build of the Docker container, the following set of commands must be typed, this is how the process progresses:
- tensorflow/tools/ci_build/ci_build.sh PI-PYTHON3\
- tensorflow/tools/ci_build/pi/build_raspberry_pi.sh
Then you need to run these commands to enable build compatibility with any Raspberry device:
- tensorflow/tools/ci_build/ci_build.sh PI\
- tensorflow/tools/ci_build/pi/build_raspberry_pi.sh PI_ONE
At the end of the complication, which on average lasts about 25 minutes, a new file is generated, it must be copied and installed on the Raspberry board:
- pip install tensorflow-version-cp35-none-linux_armv7l.whl
Downloading them from the Internet
This is a similar way to how we would do it in Windows, but to complete this task it is important to have the Raspberry as a desktop computerwith monitor, keyboard and mouse.
Then, perform the following steps:
- Open the browser of the internet on your Raspberry.
- Find the app that you want to install.
- Download.
- press twice about the package (must be .deb).
- Surely, the installer will do other secondary downloads.
Once the file is downloaded, You can also do the installation from the command console.
That is why we have told you that you must handle this form of installation well:
- Opens the terminal command.
- sudo dpkg -i name_of_file.deb, this will do the facility.
- Must have a message with the result of the procedure.
List of the best programs that you can install on a Raspberry Pi to get the most out of your miniature computer
As we mentioned at the beginning, there are a number of applications that are essential for anyone. Plus if you are an end user who wants to convert your board into a desktop computer.
Let’s see some of them below:
vlc player
This renowned multimedia player could not be missing from the list of the best applications. This is because almost all the operating systems on the Pi are based on Linux. Therefore, it is likely to use VLC as a player because it consumes less physical resources than the rest of the packages to fulfill its function.
kodi
It is a powerful program that allows you to play videos and live broadcasts. Along with VLC Player, the board has everything that is required for people to have a multimedia center in their handswith 4K playback capacity if it is a Raspberry Pi 4, which is the only one adapted for this purpose.
Synaptic
No offense intended Raspberry Pi OSbut it must be said that this program manages packages and solutions better than the native APT of the plate. Compatibility issues are better fixed and it also works from the Raspbian command terminal, as this operating system was known before.
chromium
This should be the first application you should install on your Raspberry. It is one of the best browsers you have on this boardit does not consume many RAM resources and it is easy to use.
It is usually within the Raspbian system, in its latest versions, but if it is not, then it must be installed from the terminal:
- sudo apt-get update
- sudo apt-get upgrade
DosBox
It’s a fantastic game emulator that allows people to make selection of various titles and run them for the enjoyment of the people. It’s like RetroPie is installed with various arcade games. Given the limited hardware capabilities of a Pi, there won’t be impressive graphics, but there will be entertaining titles.
