Version '2.11-1' for 'libjansson4' was not found

hello, I enter the following command to install the prerequisite packages for installing the DeepStream SDK, but it hint Version ‘2.11-1’ for ‘libjansson4’ was not found, And there are other problems , because my jetpack version is R.28.2.1, it can only support deepstream 1.5,Where can I download it deepstream 1.5?

Hi liey_job,

Please move to install the latest JetPack 4.2.2 to use with DeepStream SDK 4.0.
