Setup Raspberry Pi

  1. Update Raspberry Pi
    • Let's update the Pi just for good measures. Run the following from a terminal window -
    • pi@raspberrypi:~ $ sudo apt-get update
    • pi@raspberrypi:~ $ sudo apt-get upgrade
    • Configure SSH (if you want to be able to login to your pi remotely - coming soon)
    • Configure VNC (configure VNC to remote desktop into your Pi - coming soon)
    • Check your nodejs version. I found that dotnet build would not work for templates that needed node (angular, react, etc) because my node version was outdated
    • pi@raspberrypi:~ $ sudo nodejs -v
    • Ideally our previous sudo apt-get upgrade command would have updated node for us but I found this to not be the case. My Pi kept picking up legacy versions of nodejs. If you have a 4.xx version of node I suggest you upgrade using the following stack overflow post.
  2. Install .Net Core Pre-requisites
    • I've seen posts where people installed .Net Core on their pi without any of the following requirements but my pi has always needed most of these to be installed.
    • pi@raspberrypi:~ $ sudo apt-get install htop wpasupplicant libunwind8 libunwind8-dev gettext libicu-dev liblttng-ust-dev 
libcurl4-openssl-dev libssl-dev uuid-dev
  3. Install .Net 2.1 sdk
    • create a dotnet directory in opt to house your dotnet core installation
    • pi@raspberrypi:~ $ sudo mkdir /opt/dotnet
    • Download the arm sdk. On your Pi, go to https://www.microsoft.com/net/download/linux and download the arm32-sdk bits
    • Locate your the file you just downloaded (dotnet-sdk-2.1.300-linux-arm.tar.gz) and run the following command to unpackage the tar
    • pi@raspberrypi:~ $ sudo tar -xvf dotnet-sdk-2.1.300-linux-arm.tar.gz -C /opt/dotnet
    • Create a symbolic link so you can run "dotnet -command" from anywhere on your terminal
    • pi@raspberrypi:~ $ sudo ln -s /opt/dotnet/dotnet /usr/local/bin
    • Check to see if your installation worked by running the following commands - 
      pi@raspberrypi:~ $ dotnet --info
    • Additionally, if you get some errors running dotnet commands, you can check if you are missing any pre-requisites
    • pi@raspberrypi:~ $ cd /opt/dotnet/
pi@raspberrypi:~/opt/dotnet/ $ ldd dotnet
    • Any object that is not found means the dependency needs to be installed likely using apt-get
    • Run this command to further check for missing dependencies and be very sure you're not missing anything
    • pi@raspberrypi:~ $ cd /opt/dotnet/Microsoft.NETCore.App/2.1.0
Pi@raspberrypi:~/opt/dotnet/shared/Microsoft.NETCore.App/2.1.0 $ ldd *.so
pi@raspberrypi:~/opt/dotnet/shared/Microsoft.NETCore.App/2.1.0 $ ldd *.so|grep -i "not found"
  4. SQLite Setup
    • Install SQLite on your raspberry pi
    • pi@raspberrypi:~ $ sudo apt install sqlite

Thank You's
