my installation steps: 1. i download the jetson nano developer kit SD Card image and write it on sd card. Image link has taken from [Getting Started With Jetson Nano Developer Kit | NVIDIA Developer](https://developer.nvidia.com/embedded/learn/get-started-jetson-nano-devkit) 2. run the jetson nano with the sd card. 3. make network setup (wifi dongle detected automatically) and login/password setup at first login 4. open terminal and write “apt-get update”, result shown in my first message. how i try to solve the problem: 1. i tried to clean apt hash by ```auto sudo apt-get clean sudo mv /var/lib/apt/lists /tmp sudo mkdir -p /var/lib/apt/lists/partial sudo apt-get clean sudo apt-get update ``` 1. i tried to delete and than get new signature 3B4FE6ACC0B21F32, i tried to update the signature by ```auto sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 3B4FE6ACC0B21F32 ``` 1. i tried to take new sd card and made all steps with new sd card, result is the same. 2. I searched reason of “Hash Sum mismatch” error, but couldn’t find answer that worked for me. ---

We will try to repro this issue on our side. In the meantime, would you minding trying sdkmanager? If sdkmanager could work, it may indicate the package on download center has some problem. ---

Hi, sdkmanager(jetpack) is a tool on your desktop host. You could install it from our website. > **[JetPack SDK](https://developer.nvidia.com/embedded/jetpack)** > > Builds end-to-end accelerated AI applications and supports edge AI development. sdkmanager should automatically install the same rootfs as what you did on your sdcard. Normally, you could install it from either sdkmanager or using the package from our download center. I just suspect there are some problem when you dealt with the package. ---

For a “first boot and configure” for a new Jetson Nano 2G, (Jetpack 3.5), I encountered the same “unable to install python3-pip” problem and also discovered incomplete apt-update and apt-upgrade runs, using the NVidia supplied USB WiFi adapter. As suggested, using an Ethernet cable to connect to my network and the internet solved the problem. Anybody suggest why? Are updated WiFi device drivers required? The WiFi connection seems to work for ordinary browsing. ---
