Aceon Copier 2.23 one-click install

Preferred install:
1. Double-click "ONE CLICK INSTALL ACEON COPIER 2.23.desktop".
2. If Linux asks whether to run it, choose Run.
3. Enter the computer password only if Flatpak needs to be installed.
4. Wait for "Aceon Copier 2.23 is installed".

Fallbacks:
- Double-click "INSTALL ACEON COPIER 2.23.sh" if the desktop launcher is blocked.
- Double-click "Aceon-Copier-2.23-Linux-Debian.deb" to use the Debian/Ubuntu/Mint graphical package installer.
- In Terminal, run: bash "INSTALL ACEON COPIER 2.23.sh"

The installer verifies the Flatpak checksum before installing, can install
Flatpak through apt-get, apt, or nala when administrator permission is available,
removes older Aceon Copier user Flatpak branches, and then installs the new
version.
