pulling the 64 bit image gives you the 32 bit image, 3.20.2 doesn't have this issue, it's only 3.20.3

[fossdd]

Try clearing your docker cache or use --pull=always. Otherwise if you still have this issue you should ask in community support channels or open a issue at https://github.com/docker-library/official-images

[pennytextures]

Ignore the cached aspect, that's not the issue, a fresh pull still gives you the 32 bit image.

[fossdd]

Well it works on my end, please check your cache (e.g. other images in your local cache with the alpine:3.20 tag) or addional configuration:

$ docker system prune -a -f

it's resolved now, there was an upstream docker cache I had to clear out.
