Application installation

 

We open the terminal and log in as root:

user @ auxtral: ~ $ su (hit enter)

password: (we enter the root password) (remember that while you write you don't see it but it is entering) (enter); Now the prompt will look like this:

root @ auxtral: / home / user #

If before installing a package you want the terminal to show you a brief review of it:

root @ auxtral: / home / user # apt show packagename

We update:

root @ auxtral: / home / user # apt-get update

We install:

root @ auxtral: / home / user # apt-get install packagename

Uninstall:

root @ auxtral: / home / user # apt-get remove --purge packagename

 

 

 

 

Installation from the "Terminal"

This Software Manager is a graphical and very useful app. You access it from: "Start Menu"> "Administration"> "Software Manager".

You will see a window like the one above where the applications are arranged by categories and sub-categories. Choose the one you need and press the "install" button, or "uninstall" in case you want to remove any application that is already installed on your system and GdS does the job

".deb" packages

Appimages are an interesting way to implement applications on GNU / Linux Systems. The main feature is the "no need for installation", something like the "portables" of Windows.

Technically speaking, they are a compressed image of a stand-alone program, which carries with it all the "included dependencies" and is temporarily mounted on the system while it is running.

The most common way of executing them is having them saved in a folder that the user chooses, and giving "double click" on the file "appimage". But this way, at least I, I see it somewhat uncomfortable. that's why I'm going to show you how to do a "shortcut" in the start menu, and if you want in "the panel".

1º) The most logical thing would be to go to the "/ opt" folder, which is where "Linux" generally installs third-party programs and "open it with administrative permissions".

2º) inside "/ opt" we create a folder with the name of the application, for example "krita".

3rd) we go to the folder where we download the appimage, copy it and paste it in the folder we create: / opt / krita /

4th) Now we open the terminal (Ctrl + Alt + T) and as a current user we execute:

cinnamon-menu-editor

In Cinnamon's "menu editor" window, as Krita is an image manipulation and retouching software, we click on the "graphics" category, and in the window that appears on the right we click on "new item" .

6º) The window that follows, will appear with the fields in white, put the "name" with which it will be shown in the menu, in "command" press "browse" and look for the folder where the app is , / opt / krita /, select the appimage and accept, to finish clicking on the icon (by default you will see a rocket), and search for example in / usr / share / icons / xxxx / apps / 48x48 /, an icon representative of the application, and finally you return to "accept" in the "launcher properties" window.

We return to the Cinnamon-menu-eitor window, "Krita" already appears.

Close the window and enter the Start Menu:

You can start the application from there or right click and add it to the panel.

 

 

"Tar.gz" packages

 

Some third-party applications for Linux can be downloaded from the web in the form of .tar.gz packages; .gz; .tar.gz2, etc. These packages are generally not ready to be installed as they must be compiled beforehand.

I opened the file explorer to find the .tar.gz or similar file that you downloaded, right click on the file and select "Extract Here" and open the extracted folder.

To build or install the package you have to enter a series of commands in a terminal window. Once inside the extracted folder, do "right click" and select "open in a terminal" and it will open the terminal / console already positioned in that folder. Read the README or INSTALL file provided by the manufacturer that should be in the same folder and enter the commands as indicated. With this the application would have to be installed; Look for it in the applications menu.

If it throws you an error during the installation process, I recommend that you contact the author of the package to fix the problem.

 

Files with a .deb extension are the software packages used by Debian and its derived distros, something like Windows .exe.

You look for them in the folder where you downloaded it, or you have saved it, open the folder with a right click, in the pop-up menu click on "open with administrative permissions", enter the password "root" and right-click again on the .deb package, in the new pop-up click on "open with gdebi package installer", the gdebi installer will take care of the software installation and its dependencies if they are found in the repositories.

Gdebi (on Debian systems) is something like the Windows equivalent of the famous "Windows installer"

"Appimage" packages
Installation by downloading software packages

This method is used fundamentally for two reasons, one is that the software that we want to install is not in the repositories of our distribution, the other is the case that there is a newer version than that of our repository, and we want to install the latter. , which is not advisable.

When we use this way of installing a software package, it is recommended to download it directly from the source of the "author" of the same, since if we do it from others we could have dependency problems or system breakdown, even if we downloaded them. Debian repositories, but from a version that is not stable, in our case "buster".
