Getting Galactic Civilizations III working on Linux

Galactic Civilizations III works on Linux with the help of Valve’s unique Proton technology, which is built into the Steam for Linux client. As a result, we’ll need to go over how to install the Steam for Linux client.

Install Steam

To start the installation of Steam for Linux, open up a terminal window. Open up a terminal window on the desktop and press Ctrl + Alt + T on the keyboard. Alternatively, use the app menu and search for “terminal” to open it.

When the terminal window is open, the installation of Steam can begin. Using the instructions below that corresponds with the Linux operating system you currently use.

Ubuntu

To set up the Steam for Linux client on your Linux PC, use the apt install command below.

sudo apt install steam

Debian

To get the latest Steam working on Debian, you’ll need to download the DEB package to your computer. Using the wget command below, grab the newest Steam DEB package.

wget https://steamcdn-a.akamaihd.net/client/installer/steam.deb

After downloading the latest Steam DEB package to your computer, the installation can begin. Using the dpkg command below, install Steam on Debian.

sudo dpkg -i steam.deb

Now that Steam is installed on Debian use the apt-get install -f command below to correct any installation problems that may have occurred.

sudo apt-get install -f

Arch Linux

Steam is available for users on Arch Linux through the “multilib” software repository. To set it up, start by opening up the /etc/pacman.conf file. From there, locate the “#multilib” line, and remove the # symbol from it, as well as directly below it. Then, save the edits.

After exiting editing, use the pacman command to re-sync with the official Arch Linux servers. After that, use the second pacman command to install the latest release of Steam.

sudo pacman -S steam

Fedora/OpenSUSE

If you’re using Fedora and OpenSUSE, you’ll be able to install Steam out of the box from software sources included in their respective operating systems. However, the Flatpak release of Steam works much better on Flatpak. We suggest following those instructions instead.

Flatpak

To get Steam working via Flatpak, start by installing the “flatpak” package. To install the Flatpak package, use the package manager on your computer. If you’re having issues setting it up, please follow our guide on the subject.

After setting up the Flatpak runtime on your Linux PC, use the two commands below to get the Steam app installed.
