How to install offline a software/package in Linux?

On: Ubuntu 20.04 LTS

Since Canonical uses dpkg as their package manager, their software often ends with the .deb extension.

1. Go to the official Ubuntu packages.
2. Find your desired Ubuntu .deb package by browsing the appropiate Ubuntu version that fits your need or by searching the name of the package.
3. Once you found the Ubuntu package, choose the nearest mirror to your location in order to download the package (North America, Europe, Asia, etc.).
4. Install your .deb package using:

sudo dpkg -i the-name-of-your-deb-package.deb
