First things first
If you use apt-get install to install with a package name, it may not be registered in the repository by default and cannot be installed.
In this article, I'll use an example of installing iozone3.
Verification Environment
Debian GNU/Linux 8
Find out where the target package is located in the repository
First try to install from the list of default packages
First, try to install from the list of default packages and make sure you get a "package not found" error

Finding a repository with a package
If you put the package name in the search window, it will tell you which package it is in.

Debian's izone3 is in a non-free repository
https://packages.debian.org/jessie/utils/iozone3
Here's how to add a non-free repository to your list of repositories
Add a repository
First, check the list of the current repositories
> cat /etc/apt/sources.list
deb http://httpredir.debian.org/debian jessie main
deb http://httpredir.debian.org/debian jessie-updates main
deb http://security.debian.org jessie/updates main
Make sure there is no non-free
Install the apt-add-repository
Install the apt-add-repository package for adding a repository
# Use apt-file to find out where apt-add-repository is on the command line
> apt-get install apt-file
> apt-file update
> apt-file search apt-add-repository
# apt-add-repository is included in software-properties-common, so you can install the whole thing
> apt-get install -y software-properties-common
Adding a non-free repository
I'll add the non-free repository with the izone3 package I just examined to the list of repositories
> apt-add-repository non-free
Checking the repository list, you can see the non-free has been added to the last line
> cat /etc/apt/sources.list
deb http://httpredir.debian.org/debian jessie main
deb http://httpredir.debian.org/debian jessie-updates main
deb http://security.debian.org jessie/updates main
deb http://http.us.debian.org/debian/ jessie non-free
Installation of iozone3
I confirmed that I can install it normally using apt-get.
> apt-get update
> apt-get install -y iozone3
Confirm that the installation has been completed by displaying the version
> iozone -v
