How to Install Software on AcreetionOS: GUI, Pacman, Flatpak & AUR

Official AcreetionOS Documentation & Step-by-Step Tutorial

1. Software Management Options in AcreetionOS

AcreetionOS provides access to the vast Linux software ecosystem through multiple channels: the graphical Software Center, the native pacman package manager, containerized Flatpaks, and community packages from the Arch User Repository (AUR).

2. Installing via Graphical Software Center

For a beginner-friendly point-and-click experience:

Open the AcreetionOS Application Menu (bottom-left corner).
Click Software Center (or Add/Remove Software).
Search for your desired application (e.g., VLC, OBS Studio, GIMP, Steam).
Click Install and enter your password when prompted.

3. Installing via Pacman (Terminal)

The native package manager is fast, efficient, and direct:

# Search for packages
pacman -Ss package_name

# Install a package
sudo pacman -S package_name

# Remove a package and its unused dependencies
sudo pacman -Rns package_name

4. Installing from the Arch User Repository (AUR)

The AUR contains tens of thousands of community-maintained software packages:

# Search the AUR
yay -Ss software_name

# Install an AUR package
yay -S software_name

5. Flatpak Integration

AcreetionOS includes pre-configured Flatpak support with Flathub enabled out of the box:

# Install from Flathub
flatpak install flathub org.mozilla.firefox
flatpak run org.mozilla.firefox

6. Troubleshooting Software Installation

If packages fail to download due to slow mirrors, update your mirrorlist using Reflector:

sudo reflector --latest 10 --protocol https --sort rate --save /etc/pacman.d/mirrorlist
sudo pacman -Syu
