To properly uninstall felix86, you need to remove the felix86 binary, the rootfs, and potential binfmt_misc installations, among other things.

The uninstallation script can handle all this for you:

bash <(curl -fsSL https://install.felix86.com/uninstall.sh)

Manual uninstallation

Uninstalling from binfmt_misc

The felix86 -u command should uninstall from binfmt_misc:

sudo felix86 -u

Or, if you prefer doing it manually:

sudo rm /etc/binfmt.d/felix86-*
sudo rm /usr/lib/binfmt.d/felix86-*
sudo rm /usr/local/lib/binfmt.d/felix86-*
sudo rm /run/binfmt.d/felix86-*

Restart systemd-binfmt to finalize in the current session:

sudo systemctl daemon-reload
sudo systemctl restart systemd-binfmt

If you don’t remember the rootfs path, it can be obtained with felix86 --get-config general.rootfs_path:

felix86 --get-config general.rootfs_path

If the rootfs lives inside /opt/felix86 you can skip this step.

sudo rm -rf /path/to/my/rootfs

The felix86 profile files are stored in $HOME/.config/felix86

rm -rf ~/.config/felix86

By default, felix86 will have its own history file that should be removed:

rm -f ~/.felix86_history

The global configuration file is stored in /etc/opt/felix86/config.toml

sudo rm -rf /etc/opt/felix86

The felix86 binary itself, thunks, and any other tools exist in /opt/felix86:

sudo rm -rf /opt/felix86

sudo rm /usr/local/bin/felix86

  xdg-icon-resource uninstall --mode user --context apps --size "$size" offtkp-felix86
done

If you installed the felix86 MangoHud fork using https://install.felix86.com/mangohud.sh, you will need to remove the installed Vulkan layer:

sudo rm /usr/local/share/vulkan/implicit_layer.d/felix86-MangoHud.riscv64.json
