                          I'm using PopOs 21.10 and use the latest dotnet versions

Now I have to install the previous version dotnet core 3.1 

I tried

    wget https://packages.microsoft.com/config/ubuntu/21.04/packages-microsoft-prod.deb  -O packages-microsoft-prod.deb

     sudo apt-get update; \
       sudo apt-get install -y apt-transport-https && \
       sudo apt-get update && \
       sudo apt-get install -y dotnet-sdk-3.1

but get the error

> E: Unable to locate package dotnet-sdk-3.1

> E: Couldn't find any package by glob 'dotnet-sdk-3.1'

I also tried to change the package name

     sudo apt-get update; \
       sudo apt-get install -y apt-transport-https && \
       sudo apt-get update && \
       sudo apt-get install -y aspnetcore-sdk-3.1

but get similiar errors. When downloading the tar archive I run these commands from inside the downloads directory

    mkdir -p $HOME/dotnet && tar zxf dotnet-sdk-3.1.419-linux-arm64.tar.gz -C $HOME/dotnet
    export DOTNET_ROOT=$HOME/dotnet
    export PATH=$PATH:$HOME/dotnet

but even after restarting I can't find any 3.1 version on my machine. Would someone mind helping on how to install previous versions without removing other ones?
