Hey, thanks for the report and for pulling together links to the previous threads.

This is a known issue. The build pipeline isn’t publishing the *-web.tar.gz artifacts to blob storage. It affects all platforms, not just Linux ARM64. The team is aware, but there’s no ETA for a fix yet.

Unfortunately, there’s no way to manually download the linux-arm64-web artifact. It simply doesn’t exist on the CDN.

The only workaround right now is to use SSH remote instead of serve-web. I’ve passed your report along for prioritization. Every new thread helps.

Let me know if you have any questions.

Hi @dd7!

Just wanted to let you know that we’re removing serve-web in an upcoming version of Cursor. It was built before https://cursor.com/agents gave users a full Web UI for running agents. If there’s a use-case we aren’t meeting, definitely share your feedback!
