it looks like the build didn’t complete because your bash terminal has the wrong prompt.
Can you try to run Dev Container Rebuild and Reopen again? When it runs it will show you a dialog in the corner with a link “Show Log” and you should click that link so you can monitor the log.
When it is done, the last thing it should do is this:
Extension ‘coderoad.coderoad’ v0.17.2 was successfully installed.
If that’s not at the end of your log, something went wrong. You may have to clean up your docker environment and create a new workspace to try the steps again.
I’ve documented how to do that (I found a way through trial and error) but it is written for people who use wsl2 on windows as that is what I use (wsl is a the linux virtual machine on windows).
If you want, you can try my steps if you have wsl2 installed. And if you don’t, you can translate my steps into the equivalent steps for windows powershell.
Here’s the link to my steps:
