Linux installation

  • Download the Linux installer.
  • Open a terminal and run the installer by giving the following command:
bash ~/Downloads/va-install

Here, ~/Downloads is the directory you saved the installer into. The VisionAppster platform will be installed to your home directory (user scope) by default.

The VisionAppster platform for Linux is distributed as a Flatpak to cover as many Linux distributions as possible. The installer will inspect your system and try to install a recent enough Flatpak if needed. We haven't tested all Linux distributions. If the installer fails, please check the official Flatpak site for distro-specific installation instructions.

The va-install script is used as a maintenance tool. You may want to make it available globally to ease future maintenance tasks. In the terminal, give the following commands:

chmod +x ~/Downloads/va-install
sudo cp ~/Downloads/va-install /usr/bin

Once this is done, you can update your local or system-level installation by just entering va-install or va-install --system on the command line. Type va-install --help for usage instructions.

The installer will add desktop entries that will appear somewhere in your start menu/launcher depending on your desktop environment. There is a known caching issue in some KDE versions that prevents you from seeing the new entries unless you log out and in again. You can however always start the Builder from the command line:

flatpak run com.visionappster.VisionAppster

To start the graphical Launcher app:

flatpak run --command=va-launcher com.visionappster.VisionAppster

To start and stop the Engine systemd service:

# User scope installation
systemctl start --user va-engine
systemctl stop --user va-engine
# Some systemd versions have problems with stop, so this may be needed:
pkill va-run

# System scope installation
sudo systemctl start va-engine
sudo systemctl stop va-engine
