Unity 2019.1.11f1 Crashes with NuiTrack

I’m using Ubuntu 16.04, Unity 2019.1.11f1, latest version of NuiTrack for application testing.

I was just trying to check the tutorials and while running Unity crashes.

Unity is working fine for other applications in Ubuntu 16.04.
NuiTrack latest version is installed and activated with trial license.


Hi Prasanna,

Do you have any errors in Unity log? Is any error displayed when Unity crashes?
We’ll investigate this issue.

Yeah, It was crashing again and again without any message. After reboot and command line library linking, it stopped. Don’t why.

But a new problem is Unity application freezes after 3-4 second.

LicenseNotAcquiredException: NuitrackException (LicenseNotAcquiredException)
nuitrack.NativeImporter.throwException (nuitrack.NativeImporter+ExceptionType type) (at :0)
nuitrack.NativeNuitrack.Update () (at :0)
nuitrack.Nuitrack.Update () (at :0)
NuitrackManager.Update () (at Assets/NuitrackSDK/Nuitrack/Scripts/NuitrackManager.cs:371)

  1. Did you activate Nuitrack? What license type do you use (trial, perpetual…)?
  2. Did you manage to run standard Nuitrack samples (for example, nuitrack_sample)?

Yes, Nuitrack activated. Trial License.

No. Standard samples are not working.

  1. Did you generate your Trial key in your Nuitrack account or copy it from another PC? Trial key should always be generated and applied to only one PC (one license - one PC, second license - second PC, etc.).
  2. Please run the command ls -al /usr/etc/nuitrack/ to check permissions for data folder. If you see root root for this folder, then run the command sudo chown -R $USER:$USER /usr/etc/nuitrack/data to grant permissions.
