Visual Studio extension broken / misconfigured?

[Sjors]

I installed the Ledger's VSCode developer tools extension on an Ubuntu 25.04 desktop machine, which has Podman installed.

I clone the repo and open the develop branch @ fec3cf4.

(I cleaned podman of earlier attempts using podman stop, podman rm and podman system prune --all)

I then launch Visual Studio and open the project.

The extension initially says "No Ledger app detected in the workspace", but after a few seconds and CPU fans, it finds it.

I set the target to Nano X and variant to bitcoin_testnet. I change "release" to "debug".

Then I click on Build [debug], which fails with some permission errors, as well as a strange "[WARNING] Found duplicate files in SDK and APP":

The repo for the extension is LedgerHQ/ledger-vscode-extension if you want to report issues, as I don't think there's anything specific to this app (although this app was created much earlier than both the app-boilerplate and the extension that more recent apps are based on - so there might be things that need modernizing here).

I did experience the annoying Permissions denied issue in other codebases, probably caused by docker usage. Deleting (with sudo) the build/target folders does it for me (but it might happen again every once in a while 🤷).

As for the features of the extension, I normally use it at most for building and loading the app on the device (not on Nano X) - then I run speculos separately because I don't want to deal with docker madness.

Ok, I'll try some other "crypto" apps to see if the issue is indeed in the extension and not here.

Do you mean build/target inside the app-bitcoin-new repo? Those would have wiped with git clean -dfx. Or inside the Docker container? But I wiped those too.

because I don't want to deal with docker madness

Neither do I, but I'm having a hard time figuring out how to build the app without Docker, as the README points to that...

Maybe #348 is more productive approach :-)
