If you see a fatal sandbox error mentioning chrome-sandbox not being owned by root or missing mode 4755, your system's AppArmor or kernel settings are blocking the Chromium sandbox. There are two ways to fix this:
Option A — Pass --no-sandbox (quickest)
Run the AppImage with the sandbox disabled:
./PokeRogueOffline.AppImage --no-sandbox
Option B — AppArmor unprivileged user namespace (recommended)
On Ubuntu 23.10+ and other distros that restrict unprivileged user namespaces, you can create an AppArmor profile that allows the AppImage to sandbox itself properly without disabling security globally:
sudo aa-status | grep apparmor
If AppArmor is running, create a profile to allow user namespaces for the AppImage:
sudo tee /etc/apparmor.d/pokerogue-offline <<'EOF'
abi <abi/4.0>,
include <tunables/global>
profile pokerogue-offline /path/to/PokeRogueOffline.AppImage flags=(unconfined) {
userns,
}
EOF
sudo apparmor_parser -r /etc/apparmor.d/pokerogue-offline
Replace /path/to/PokeRogueOffline.AppImage with the actual path on your system. After running, launch the AppImage normally without --no-sandbox.
