Hi,

I received a problem with my graphical network simulator gns3. A screenshot of the message is as below. I do not understand the message. How can I fix it? Please help.

Untrusted application launcher

Untrusted application launcher

The application launcher "gns3.desktop" has not been marked as trusted. If you do not know the source of this file, launching it may be unsafe.

Try loading your gns3 application from the folder in which it is originally installed. This might be a shortcut issue. If no error message is received while loading from an original gns3 folder (where this app has been installed) then you can create a new shortcut for this application by right click on gns3 icon and navigating to send to, desktop (create shortcut).

Hopefully this will solve your problem.

Hello.

This dialog box is for your security purpose only.

To overcome with this problem you need to do the following things.

  • Right click on the application launcher.
  • Select properties and in properties select permissions tab.
  • In the permissions tab find the check box allow executing file as program as shown as below figure.
Allow Executing file as Program
  • Now Ubuntu will stop showing the error message.

Thank you.
