Did you reboot after adding the application file to /usr/share? Do other icons show up on your desktop? Did you change the permissions to make it executable? Try disabling and enabling the desktop icons extension.
If you mean like a Self Installing Package, that would be any *.deb package, where the * stands for the package name.
But not every independent developer creates a package as a .deb. This is true on Windows, too, where not every independent developer puts a product out as an .exe
I had to install some stuff using Ninja in the CMD Prompt on Windows.
Not at all, no. They have no meaning because they are new to you. Just as "regedit" in the CMD prompt on Windows might be new to you at some point.
But once you learn them, they are familiar and known and have meaning.
sudo: SuperUserDO as in, "Do This". This elevated you to Admin Privileges.
apt: The package management and supplier of software
Update: Updates your sources so you know you are getting the latest available software
install: This is self explanatory.
add-apt-repository: The terminal does not like whitespace or spaces between words that are part of a whole. So, we replace those spaces with a dash reserving spaces to separate terminal commands.
add-apt-repository is the command to add the repository to your apt sources to allow you access to the software that repository contains.
It is very confusing to users coming to Linux now. There are three different package management systems at work, right now and they are each competing with each other. I rely solely on APT and I do not use Flatpak or Snap.
Flatpak and Snap offer advantages... and disadvantages. APT is the Standard package management system in use.
Thanks, I really appreciated it. I would love to leave MS after 35 years and use Linux.
I'm very pleased that I don't have to use Terminal, but I must admit I often use Windows prompt really to have something done efficiently. Maybe because I started years before Windows slowed almost everything down.
"package management system" is a install system..?
When ATP is standard I'll try my best stay there. I wish there was a standard distro beside all kind of distros.
One of the many reasons I will try Linux are that I'm tired MS telemetry and the way they treat customers. 66% of my install time of a new Windows install are used to remove all kind of nasty stuff.
ok *.deb package: So If you have to find such a package the developer will announce that..?
This is the same reason I prefer and use the terminal.
It is fast, efficient and once you learn it, easy to use.
You can search packages with it, both installed and available. Convert files and packages, move them, copy them, etc.
Yes, like "Add and Remove Software."
Often, developers do announce their packages. You can look for their github page or if they have their own webpage. For example, looking for a .deb package from a developers webpage may include looking at the Brother Printers Website.
