How to get the latest ubuntu image for Beaglebone Black (via MicroSD Card)?

OK, I’ll try that this evening, and also a new SD card.
Is a 64GB card fine for the BBB?

BTW, what are the main differences between versions 10 and 11? Is it worth the effort?

EDIT: looking at your suggestion, I see that the size of the image file is only 775MB, which is very small compared to the ones I tried (more than 3GB). Is this normal?

Furthermore, I downloaded the image from here, but it says:

Media AM335x Xfce Snapshot
microSD Download am335x-debian-11.5-xfce-armhf-2022-11-01-4gb.img.xz 10
microSD sha256sum 7744b99569073a5c6282ec7627778161f2abe47f985500c5c40300ae8c2b8c97

The media is microSD, not eMMC. Maybe this is not the correct file?
