Troubleshooting Graphic User Interface Issues on *nix Systems
To use the graphic user interface of Software AG Update Manager, first your system needs to be properly configured to run software with graphic user interface. If an issue occurs with running the Update Manager graphic user interface, make sure your that your system is not missing any essential libraries by, for example, running a different product with a graphic user interface.
If the problem persists after installing all libraries required by your operating systems, try the following solutions:
Check your internet connection. Issues might be caused by a network timeout or a delay in VPN communication.
Install missing xlib libraries that are required by your operating system. The
Update Manager startup error message might contain information on which xlib libraries are missing.
Check whether xclock is installed on your machine and install it if necessary.
