Hi Ubuntu Mate and Raspberry Pi Friends,
I've downloaded and installed from the site for 18.04 Mate ( ubuntu-mate-18.04.2-beta1-desktop-arm64+raspi3-ext4.img.xz)
However, during boot, raspberry gives "the board requires newer software, get the latest software from .... " as shown in below image:
Hope to get your expertise on the issue.
