An error occurred while automatically activating bundle com.digi.xctung on Ubuntu 18.04

I downloaded XCTU v6.5.1 for Linux x86_64, and installed.
Following error message is coming when launched:

Are you logged in as the Administrator on this system?

Above problem is observed when the XCTU application is launched by the XCTU Setup Wizard.
No such problem is observed when I launched the XCTU application as a super user.

Thanks for your hint.

Launch the XCTU application as a super user.

That would explain why. You don’t have the needed permissions to run a installer.

Infact I launched the installer too as a super user, using following commands.

$ sudo chmod +x ./40002881_X.run
$ sudo ./40002881_X_XCTUv6.5.1_Linux64.run

At the end of installation - setup wizard launching the application, but failed to launch.

I launched the application with the following command:
$ sudo ./app

I get the error when attempting to use the script with sudo as well. You can’t run it as the normal user, it will shut you down trying to install in /opt/Digi.

Going to try an install it in the /home/user directory as the user to see if that works.
