Installing Programs on Linux Mint 17.3 Cinnamon: Package Not Found, Sudo Apt-Get, Make Install

Does the downloaded program file have the "executable" attribute set so that you can run its installation?

You need to know Linux basics if you want to install packages this way.

Added after 5 [minutes]:

Until then, it remains to install ready-made .deb packages, e.g. using this method (ready recipe for incentive):

i don't know what that means, where can i check it?

You right-click on the file and select the file's properties from the context menu. In the window that opens, select a tab Permissions and check and mark the option if necessary Permission to execute a file as a program as in the picture below.

In the console, go to the folder with the downloaded and unpacked program and enter the command:

an administrator password is required. If you have difficulty navigating in the console text mode, install the file manager - Midnight Commander with the command in the console:

To avoid typing the long filename AESCrypt-GUI-3.10-Linux-x86_64-Install, you can select this file in Midnight Commander and then press left alt + entrer. The filename will be copied to the command line of the Midnight Commander. Of course, we enter beforehand sudo ./ . For me, the installation in Linux Mint 17.3 64 bit starts as shown below.

It depends on the form in which the program is made available. The easiest way to install programs is through the Linux distribution's software repository. However, not all programs are available in it. Other programs are available in the form of ready packages with the * .deb extension (Debian and its derivatives), * .rpm (Mandriva and its derivatives), etc. Then you click on the program file and install it a bit like in Windows. Missing packages and libraries for the operation of a given program, the system most often in this case can reinstall itself. Of course, you need an administrator password. Yet another way is the one presented here by means of the console and its commands. The most difficult way to "install" programs is to compile the programs themselves from source. It happens that some programs need additional packages or libraries to work, which need to be additionally installed, which sometimes makes the installation of programs difficult. When installing a program from the console, messages about incompatible package versions, missing or needed additional packages are displayed. Then you have to put more effort into installing such a program.
