This question already has an answer here:
When updating I got the following message:
W: An error occurred during the signature verification. The repository is not updated and the previous index files will be used. GPG error: http://dl.google.com/linux/chrome/deb stable Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 6494C6D6997C215E W: Failed to fetch http://dl.google.com/linux/chrome/deb/dists/stable/Release.gpg The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 6494C6D6997C215E W: Some index files failed to download.

I'm on Ubuntu 16.04 and currently using Chrome 60.0.3112.90. Any suggestions? I'm also trying to install libimobiledevice but apparently the system is not reading the repository where I just added the PPA as I can't install it. Thanks in advance for any help.
