Right, for the key issue, that has taken me right back to where I started: W: There is no public key available for the following key IDs: 1397BC53640DB551
Odd. If you do a web search with that number, you'll find a lot of posts mentioning this issue and all of them point to the same fix: get google's new key (file).
Possibly stupid question -- this is Jessie, does this mechanism of dropping the files in trusted.gpg.d work properly in Jessie or is it new?
Good question. Sven said it worked. I can't confirm that. It may be worth to try to import that key directly from a keyserver, like I suggested in my first reply:
sudo apt-key adv --keyserver keys.gnupg.net --recv-keys 1397BC53640DB551 Regards, Frank
