22.04.4 Download Link Redirects to Wrong Architecture.

[woohyun7878]

Operating on Apple M1 MacBook Pro, Chrome browser.

The following button should redirect to arm64 architecture for my device, but actually redirects to https://ubuntu.com/download/desktop/thank-you?version=22.04.4&architecture=amd64. This behavior is reproducible on macOS.

Thanks for reporting this. I believe it's working now?

Hi, the issue persists on my M1 device with a clean cache both on Chrome and Safari.

How are you detecting user architecture? I believe that some browser features are obsolete for compatibility reasons^{1 2}. For example, the following is my local navigator.userAgent String:

Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/123.0.0.0 Safari/537.36

However, I am definitely operating on an M1 chip.

I see. I don't think we have anything in place to detect architecture. Feel free to contribute.

Even if we did detect architecture, there are no generic arm64 desktop images to download. There are specific pre-installed images like the Ubuntu Desktop for Raspberry Pi, but there's nothing this button could reasonably point to in the general case (currently).

Oh, apparently there are generic arm64 images now! Not sure they'd work on the Apple hardware, but I guess we should link to them somehow.
