Can't download RISC-V SDK for 2.19.0-374.2.beta or 2.19.0-374.1.beta

[cpswan]

• Dart SDK Version: 2.19.0-374.2.beta or 2.19.0-374.1.beta
• Linux on RISC-V
• wget (and Chrome)

I went to the Dart SDK archive to download the latest SDK for RISC-V. The latest release 2.19.0-374.2.beta and the previous release 2.19.0-374.1.beta both result in the following type of error from GCS:

<Error>
<Code>NoSuchKey</Code>
<Message>The specified key does not exist.</Message>
<Details>No such object: dart-archive/channels/beta/release/2.19.0-374.2.beta/sdk/dartsdk-linux-riscv64-release.zip</Details>
</Error>

With wget this gets reported at ERROR 404: Not Found.

The last working version appears to be 2.19.0-255.2.beta

Hi, the Dart SDK is not yet officially supported on RISC-V and as such we currently only publish builds on the dev channel and not beta and stable until it's ready. Thanks for helping by trying it out! :)

The 2.19.0-374.2.beta release branched off 2.19.0-374.0.dev, so you could download that version instead and only miss out on a single cherry-pick.

It looks like a bug on our dart.dev website that it includes RISC-V in the beta channel, but correctly omits it from the stable channel. Likewise with the Windows ARM64 build that is also only on dev. We'll fix the website to avoid confusion :)

Thanks for the clarification @sortie

From conversations in the community I think a lot of people were under the (mistaken) impression that RISC-V was further along than it is given that it was appearing as a beta. Having kicked the tyres a little today (and looked at where things are with upstream dependencies for Docker support like Debian) it doesn't feel oven ready yet (and arguably Windows Arm64 is a more stable target that I'd expect to progress through beta to stable first).

@cpswan It was added by mistake to beta before being ready that's why it showed up for some versions. This has been fixed. We currently have no test coverage for RISC-V, so we don't know how well it works and wouldn't know if it breaks. Until we have coverage (and it works well enough), RISC-V will remain on main and dev channels only.

@athomas were RISC-V builds intentionally promoted to stable channel from 3.3.0, or has there been another glitch in the matrix?

It's intentional, see https://dart.dev/get-dart#system-requirements
