Develop .NET 5 on Codespaces

Question

Is it possible to use dotnet 5 on Visual Studio Codespaces? I have followed the instructions for ubuntu 18.04 found here https://learn.microsoft.com/en-us/dotnet/core/install/linux-ubuntu#1804-

After running:

sudo apt-get install -y dotnet-sdk-5.0

I get the response:

Reading package lists... Done
Building dependency tree       
Reading state information... Done
dotnet-sdk-5.0 is already the newest version (5.0.100-1).
0 upgraded, 0 newly installed, 0 to remove and 39 not upgraded.

When I run the dotnet --list-sdks I get the following versions:

1.1.14 [/home/codespace/.dotnet/sdk]
2.1.807 [/home/codespace/.dotnet/sdk]
2.2.402 [/home/codespace/.dotnet/sdk]
3.0.103 [/home/codespace/.dotnet/sdk]
3.1.301 [/home/codespace/.dotnet/sdk]

Why is 5.0 not showing?

The current work around is to run:
