Thank you for reading my topic. I’m using Jetson AGX Orin in my research. I refer to " Getting Started with Jetson AGX Orin Developer Kit([Getting Started with Jetson AGX Orin Developer Kit | NVIDIA Developer](https://developer.nvidia.com/embedded/learn/get-started-jetson-agx-orin-devkit)) to setup my device. Before installing Jetpack, I have to upgrade L4T because my device’s version is R34 (release), REVISION: 0.1. I have revised the file"/etc/apt/sources.list.d/nvidia-l4t-apt-source.list" from deb [https://repo.download.nvidia.com/jetson/common](https://repo.download.nvidia.com/jetson/common) r34.0 main deb [https://repo.download.nvidia.com/jetson/t234](https://repo.download.nvidia.com/jetson/t234) r34.0 main to deb [https://repo.download.nvidia.com/jetson/common](https://repo.download.nvidia.com/jetson/common) r32.1 main deb [https://repo.download.nvidia.com/jetson/t234](https://repo.download.nvidia.com/jetson/t234) r32.1 main using vi. And I tried to execute “sudo apt update” but I failed.

I have exactly same issue in Jetson AGX Orin. If anyone have an idea how to fix this issue: E: The repository ‘[https://repo.download.nvidia.com/jetson/common](https://repo.download.nvidia.com/jetson/common) r34.1 Release’ does not have a Release file. Thank you community ---

I tried to replace: sudo bash -c ‘echo “deb [https://repo.download.nvidia.com/jetson/common](https://repo.download.nvidia.com/jetson/common) r34.1 main” \>\> /etc/apt/sources.list.d/nvidia-l4t-apt-source.list’ sudo bash -c ‘echo “deb [https://repo.download.nvidia.com/jetson/t234](https://repo.download.nvidia.com/jetson/t234) r34.1 main” \>\> /etc/apt/sources.list.d/nvidia-l4t-apt-source.list’ By: sudo bash -c ‘echo “deb [trusted=yes] [https://repo.download.nvidia.com/jetson/common](https://repo.download.nvidia.com/jetson/common) r34.1 main” \>\> /etc/apt/sources.list.d/nvidia-l4t-apt-source.list’ sudo bash -c ‘echo “deb [trusted=yes] [https://repo.download.nvidia.com/jetson/t234](https://repo.download.nvidia.com/jetson/t234) r34.1 main” \>\> /etc/apt/sources.list.d/nvidia-l4t-apt-source.list’ So I added [trusted=yes] and the following errors disappears: E: The repository ‘[https://repo.download.nvidia.com/jetson/common](https://repo.download.nvidia.com/jetson/common) r34.1 Release’ does not have a Release file. E: The repository ‘[https://repo.download.nvidia.com/jetson/t234](https://repo.download.nvidia.com/jetson/t234) r34.1 Release’ does not have a Release file. but still have other errors, tell me if it this solution works for you? ---

Thank you for kind reply. I tried your solution and might got the same result as you. The part of error disappeared. I got the following error messages. E: Failed to fetch [https://repo.download.nvidia.com/jetson/common/dists/r34.1/main/binary-arm64/Packages](https://repo.download.nvidia.com/jetson/common/dists/r34.1/main/binary-arm64/Packages) Could not handshake: The TLS connection was non-properly terminated.

I was able to let it work. If you have the same error as mine(refer to my previous reply), following solution might work. sudo vi /etc/apt/apt.conf write configuration below. Acquire::http::Proxy “[http://your](http://your) proxy server:your port number/”; Acquire::https::Proxy “[http://your](http://your) proxy server:your port number/”; if your proxy require the certification,write configuration below instead above. Acquire::http::Proxy “[http://your](http://your) ID:password@your proxy server:your port number/”; Acquire::https::Proxy “[http://your](http://your) ID:password@your proxy server:your port number/”; I appreciate your kind advice. ---

Thank you for your help, I am not quite familiar with proxy, Can you tell me how can I fill these lines according to my case? Acquire::http::Proxy “[http://your](http://your/) proxy server:your port number/”; Acquire::https::Proxy “[http://your](http://your/) proxy server:your port number/”; Acquire::http::Proxy “[http://your](http://your/) ID:password@your proxy server:your port number/”; Acquire::https::Proxy “[http://your](http://your/) ID:password@your proxy server:your port number/”; how to know my proxy server and port number and ID also? Thank you again ---

Is there someone who is in charge of proxy management in your company or university? You should ask him or her your ID, password, proxy server address and port number. your proxy might not require certification. In that case, you don’t need ID and password. So, Acquire::http::Proxy “[http://your](http://your/) proxy server:your port number/”; Acquire::https::Proxy “[http://your](http://your/) proxy server:your port number/”; is OK. Port number is generally 8080 but you should confirm. If you don’t have connection error, this solution might not work well. ---
