app commands do not work after a failed installation

Last Updated : Jun 10, 2026 |

Condition

After a failed or incomplete installation, app commands, such as app uninstall or app configure, do not work.

Cause

app is an alias command that provides a convenient way to run commonly used application-specific commands. Avaya Aura® Device Services sets up aliases, including app, during installation. If the installation process fails, aliases are not set up properly, so you cannot use them.

Solution

Procedure

Reinstall the Avaya Aura® Device Services application.

  1. Log in to the Avaya Aura® Device Services CLI as an administrator.
  2. Run the following commands to uninstall Avaya Aura® Device Services:
    cd /opt/Avaya/DeviceServices/<version>/CAS/<version>/uninstaller/
    sudo ./uninstallAADS.sh
    
  3. Install Avaya Aura® Device Services.
