failure to load repository information [duplicate]

It seems that the signature for google earth is not verified ( and it seems that its a common problem with google earth) so try the following: Setup key with:

wget -q -O - https://dl-ssl.google.com/linux/linux_signing_key.pub | sudo apt-key add - 

Setup repository with:

sudo sh -c 'echo "deb [arch=amd64] http://dl.google.com/linux/earth/deb/ stable main" >> /etc/apt/sources.list.d/google.list'

Time to update now :

sudo apt update
