To begin installing Steam on your 64-bit Ubuntu, you can use the Ubuntu Software Center, which provides a user-friendly way to install applications without needing to use the terminal. First, open the Ubuntu Software Center by clicking on its icon in your applications menu. In the search bar, type “Steam” and select the Steam application from the results. Click the “Install” button, and the system will handle the download and installation process for you. Alternatively, if you feel comfortable using the terminal, you can open it by pressing Ctrl + Alt + T and enter the command: sudo apt install steam. This will also install Steam directly from the official repositories without needing to add any extra repositories. As for compatibility issues, while most games on Steam work well with Ubuntu, some may require additional configuration or might not run at all. Always check for Linux compatibility on the game’s store page before purchasing.

Once Steam is installed, launch it from your applications menu. If you don’t already have a Steam account, you will need to create one to access the platform’s features. Click on “Create a new account” and follow the instructions. After setting up your account, you can log in and start looking for games. To download a game, simply navigate to the Store section, find the game you want, and click the “Add to Cart” button, followed by proceeding to checkout if applicable. You’ll be prompted to download the game after purchase, or you can install any game in your library by selecting it and clicking the “Install” button. There’s a user-friendly interface within Steam, so you should find it intuitive to browse, download, and launch games. Don’t hesitate to explore the settings or community forums if you need further guidance.
