Navio2 No pubkey

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

Are the new keys going to be added to the next Navio image

Hi Barry,

Where do you get this message? Could you post a screenshot of it here?

Its when I run sudo apt-get update

ROS has its GPG keys changed due to the recent security issue on their build farm. The keys included in the image are basically no more being used and you have to update them. Follow the following steps to do that:

sudo apt-get install dirmngr --install-recommends

sudo apt-key del 421C365BD9FF1F717815A3895523BAEEB01FA116

# add the new key
sudo -E apt-key adv --keyserver 'hkp://' --recv-key C1CF6E31E6BADE8868B172B4F42ED6FBAB17C654

sudo apt-get update
