On your phone, do you search the software you want to install through your browser? After which, do you download the install script and try to run it?

No, of course not. Instead, you pay a visit to the accompanied software center. Searching, installing and upgrading all occur through that.

Similarly, on Linux, your chosen distro comes with a (or perhaps multiple) package manager(s) and a software center. Those should first and foremost be consulted. And for 99% of the cases; this is the intended, supposed and supported way of installing said software.

This should suffice for the sake of brevity. If you’ve still got questions, please feel free to ask them.
