But sdkmanager shows error message as followings.

Error in local apt settings
SDK Manager received errors while using apt commands on your system.
Please check that the Ubuntu local apt repository is working well on your local system including dependencies of packages.
Review SDK Manager terminal for the specific error/s.

In termnal log I confirmed, it seems to fail install CUDA L4T toolkit.

Hi hkada,

The error indicates some unknown issue that is only to be fixed manually with your apt system. Can you please paste the detailed log (~/.nvsdkm/sdkm.log)? The detailed log will help me understand the issue better.
Can you please also let me know which version of JetPack is the NX flashed with?
