Jetson Nano - Apt Update/JetPack Install Fails with "No Space Left on Device" & Signature Verification Errors

I’m encountering issues while trying to install or update JetPack on my Jetson Nano. The system throws multiple errors related to GPG signature verification and disk space limitations, and fails to fetch required repositories. Below are the details and screenshots of the terminal output.


System Info:

  • Device: Jetson Nano (4GB)
  • JetPack Version Attempted: nvidia-jetpack
  • OS: Ubuntu 18.04 (L4T-based)
  • Installation Method: Pre-installed SD card image
  • Internet: Connected via Ethernet

    anyone please help me to resolve it.

Suggest to use SDK manager to install JetPack on your Jetson Nano from a native Ubuntu OS PC.

FYI, it looks like your network was unable to reach either the Ubuntu or the NVIDIA servers. If it is a VM, then networking has not been passed through correctly. The other part about “/var” space is probably the host side space (I don’t know for sure, it could be Jetson disk space, but it is highly likely that it is host side) is low. Often people fail to mention they are using a VM, and the VM requires far more disk space than expected and so it runs short. Sometimes people use a non-ext4 filesystem on a VM, and things appear to work, but the installation itself is bad if not based on an ext4 host.
