Basic question: Why is there a "Install RELEASE" after booting into ubuntu?

The second icon on the top left says “Install RELEASE”, like this:

What does it mean since I thought I have installed ubuntu using “sudo NVIDIA-INSTALLER/installer.sh”.

Thanks.

I’m unable to test as my desktop system is currently dead, but typically Jetson arrives with ubuntu installed and the installer is for the hardware accelerated files (those files are licensed separately from the Ubuntu distribution). I’m not really sure what that icon would do…I’d guess you can click it and see what it wants to do without actually doing it (more clicks would be required).
