Following install instruction I get the error message:

The following signatures couldn't be verified because the public key is not available: NO_PUBKEY F42ED6FBAB17C654

Installing on a raspi3 with freshly installed Buster, it was working fine on Jessi. Can anyone help? Thx.

The Raspberry Pi Kinetic instructions need to be updated with the new key in the Setup ROS Repositories step:

sudo -E apt-key adv --keyserver 'hkp://keyserver.ubuntu.com:80' --recv-key C1CF6E31E6BADE8868B172B4F42ED6FBAB17C654

Would be great if someone could actually update that page.

@Hexrobot: perhaps this would be something you could do, seeing as you just ran into the problem.
