I wonder if this might be a network / ISP issue? Could you identify the relevant URLs in https://downloads.raspberrypi.com/os_list_imagingutility_v4.json please and try downloading them in your web-browser, to see if that also results in the Ubuntu images downloading much slower than the Raspberry Pi OS images?

I can confirm this is an issue with the download links. I tried with Ubunut24 server links (for rpi4 and rp5). I'm on a 3gb fiber connection and the download is looking at 30min.

I guess you need to get in touch with your ISP then?
