This blog specifically describes the steps involved in installing .NET Core SDK 3.1 in Ubuntu 20.04 LTS Developer Machine.

1. Open a terminal and run the following commands to setup the 20.04 repositories

    sudo wget https://packages.microsoft.com/config/ubuntu/20.04/packages-microsoft-prod.deb -O packages-microsoft-prod.deb
    sudo dpkg -i packages-microsoft-prod.deb
   

2. Install the .NET Core SDK

    sudo add-apt-repository universe
    sudo apt-get update
    sudo apt-get install apt-transport-https
    sudo apt-get update
    sudo apt-get install dotnet-sdk-3.1
   

I would not recommend you to use the 19.04 repositories since the distribution has officially reached its end of life.

Issues & Workarounds

• While executing the command sudo apt-get install dotnet-sdk-3.1, you may get dependency errors related to libicu not found in Ubuntu 20.04 LTS. If this is the case, then execute the following commands in terminal [courtesy: Phillip Haydon]. Now try the sudo apt-get install dotnet-sdk-3.1, it should work.

    sudo wget http://mirrors.edge.kernel.org/ubuntu/pool/main/i/icu/libicu63_63.2-2_amd64.deb
    sudo dpkg -i libicu63_63.2-2_amd64.deb
  

You should see the microsoft docs get updated in a day or two on linux package manager instructions specifically for Ubuntu 20.04 LTS.
