Question

When working through the training exercise:https://learn.microsoft.com/en-us/training/modules/create-a-build-pipeline/3-build-locally?pivots=github-codespaces-agentSet up Codespaces; step 2 - Wait for your Codespace to build:

I get the following error:

The .NET Core SDK cannot be located: Error running dotnet --info: Error: Command failed: dotnet --info /bin/sh: dotnet: not found /bin/sh: dotnet: not found . .NET Core debugging will not be enabled.

Hi David Wilkinson,

Thank you for reaching out to Microsoft Q & A forum.    

The above error suggests that the .NET Core SDK is not installed or not correctly configured in your Codespace environment. To resolve this issue, please follow these steps: 

1.Install the .NET Core SDK: 

Open the terminal in your Codespace. 

Run the following commands to install the .NET Core SDK: 

sudo apt-get update
sudo apt-get install -y dotnet-sdk-6.0

Ensure that the version number (6.0) matches the version required for your project. If a different version is needed, adjust accordingly. 

2.Verify the Installation: 

After installing the SDK, verify the installation by running: 

dotnet --info

This command should display information about the installed .NET Core SDK. 

3.Set the Path (if necessary): 

If the SDK is installed but still not recognized, you might need to add it to your PATH. Add the following line to your .bashrc or .zshrc file: 

export PATH=$PATH:/usr/share/dotnet

Reload the terminal or run source ~/.bashrc or source ~/.zshrc to apply the changes. 

4.Retry the Build: 

Once the .NET Core SDK is installed and recognized, retry building and running the web app with the following commands: 

dotnet build --configuration Release
dotnet run --configuration Release --no-build --project Tailspin.SpaceGame.Web

Following these steps should resolve the error and allow you to build and run the web app successfully in your Codespace. If the issue persists, please provide any additional error messages for further assistance.

Problem still not resolved: See responses below from running commands:

@DaveW07 ➜ /workspaces/mslearn-tailspin-spacegame-web (main) $ sudo apt-get update

sudo apt-get install -y dotnet-sdk-6.0

sudo: apt-get: command not found

sudo: apt-get: command not found

@DaveW07 ➜ /workspaces/mslearn-tailspin-spacegame-web (main) $ dotnet --info

bash: dotnet: command not found

@DaveW07 ➜ /workspaces/mslearn-tailspin-spacegame-web (main) $ export PATH=$PATH:/usr/share/dotnet

@DaveW07 ➜ /workspaces/mslearn-tailspin-spacegame-web (main) $

On restarting terminal i get the following output:
