Hi all... I'm trying to download Ubuntu Mate to install on a Rpi3. I'm downloading it from ubuntu-pi-flavour-maker.org, which takes me to the official Ubuntu page, but when I unarchive the .xz file (using The Unarchiver on MacOs) and mount the .img file it's always EMPTY. Nothing there.
The file I'm downloading is: ubuntu-core-18-armhf+raspi3.img. Double-clicking it loads a volume called 'UBUNTU', but it's completely empty (showing '0 items, 65.9MB Available').
Are there any other sources to download from?
TIA,
