Hey there,
I am having NX Xavier SOM with the AverMedia board running JP4.5.1. I am using the device on ssh remotely but recently I noticed that whenever I am trying to install anything using the apt command, my terminal freezes and I need to log in again to the GPU.
Can you log in with serial console and run βdmesg --followsβ prior to starting the use of βaptβ? There would probably be a useful message there at the moment ssh fails.
