Tensorflow installation problem

when I was trying to install tensorflow on jetson nano following the instructions in this link Installing TensorFlow For Jetson Platform :: NVIDIA Deep Learning Frameworks Documentation when it to this command it abort aumatically sudo apt-get install python3-pip

I can’t answer the question, but you will want to repost this in the Nano forum. Legacy is from much older hardware which didn’t even have a GPU (and such hardware does not support TensorFlow). Here is the Nano forum:
