Flatpak Install Guide (Linux)

Follow the steps for your distro, then install the .flatpak file (e.g., mythicgmedigital.flatpak). Careful with copying and pasting links here--Itch forces the use of HTML tags on links it detects and I can't figure out how to turn it off.

Ubuntu 22.04 / 24.04 / Debian 12 / 11

sudo apt update 
sudo apt install -y flatpak 
flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo

Arch Linux / Manjaro / EndeavourOS

sudo pacman -S --noconfirm flatpak 
flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo

openSUSE Leap / Tumbleweed

sudo zypper install -y flatpak 
flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo

Fedora 40 / 41 / 42

sudo dnf install -y flatpak 
flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo

RHEL 9 / CentOS Stream 9 / Rocky 9 / AlmaLinux 9

sudo dnf install -y flatpak 
flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo

Install the `.flatpak` file (all distros)

Assumes you downloaded mythicgmedigital.flatpak to your current folder. The file name my be different as well.

# Install for your user (recommended) flatpak install --user ./mythicgmedigital.flatpak

(Flatpak will fetch the required runtime from Flathub if needed.)

Run the app

# Option A: from your desktop menu (after install)  
# Option B: from the terminal 
# Find the app ID (replace "mythic" with part of the app's name if needed) 
flatpak list --app | grep -i mythic  
# Then run it (replace <APP_ID> with the exact ID shown above) 
flatpak run <APP_ID>

Update / Uninstall (optional)

# Update all Flatpak apps and runtimes 
flatpak update  
# Uninstall the app (replace <APP_ID> as above) 
flatpak uninstall <APP_ID>  
# Remove unused runtimes 
flatpak uninstall --unused

Quick checks (troubleshooting)

# Confirm Flatpak is installed 
flatpak --version  
# Confirm Flathub is added 
flatpak remotes
