2021-01-15 Install pythonnet on debian is difficult

From Install the .NET SDK or the .NET Runtime on Debian.

wget https://packages.microsoft.com/config/debian/10/packages-microsoft-prod.deb -O packages-microsoft-prod.deb
sudo dpkg -i packages-microsoft-prod.deb
sudo apt-get update
sudo apt-get install -y apt-transport-https
sudo apt-get install -y dotnet-sdk-5.0
sudo apt-get install -y aspnetcore-runtime-5.0
sudo apt-get install -y dotnet-runtime-5.0

Then build pythonnet:

git clone https://github.com/pythonnet/pythonnet
cd pythonnet
python3.9 setup.py build_dotnet
python3.9 setup.py bdist_wheel

Unfortunately, pythonnet does not work with dotnet yet on linux. mono is still needed (see Add the Mono repository to your system).

sudo apt install apt-transport-https dirmngr gnupg ca-certificates
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 3FA7E0328081BFF6A14DA29AA6A19B38D3D831EF
echo "deb https://download.mono-project.com/repo/debian stable-stretch main" | sudo tee /etc/apt/sources.list.d/mono-official-stable.list
sudo apt update
sudo apt install mono-devel nuget
mono --version

The package dotnetcore2 might be needed. This is a work in progress.
