In reply to Thomas L. Harman. Looking at the error above, apt is telling us that the following key is missing: F42ED6FBAB17C654 The key should be located at /etc/apt/trusted.gpg.d/ but for some reason, it is not. You can try the following command to add the missing key: sudo -E apt-key adv --keyserver 'hkp://keyserver.ubuntu.com:80' --recv-key F42ED6FBAB17C654

$ sudo apt-get update –fix-missing
An error occurred during the signature verification. The repository is not updated and the previous index files will be used.

GPG error: http://packages.ros.org/ros/ubuntu xenial InRelease: The following signatures couldn’t be verified because the public key is not available: NO_PUBKEY F42ED6FBAB17C654
W:

Some index files failed to download. They have been ignored, or old ones used instead.

Any ideas how to fix “signatures” Thanks, Tom Harman
