I cannot install pepperflashplugin-nonfree on my Ubuntu :
$ sudo apt install pepperflashplugin-nonfree Reading package lists... Done Building dependency tree Reading state information... Done Suggested packages: ttf-dejavu ttf-xfree86-nonfree The following NEW packages will be installed: pepperflashplugin-nonfree 0 upgraded, 1 newly installed, 0 to remove and 0 not upgraded.

I have added the missing key :
$ sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com 1397BC53640DB551 gpg: requesting key 640DB551 from hkp server keyserver.ubuntu.com gpg: key D38B4796: public key "Google Inc. (Linux Packages Signing Authority) <firstname.lastname@example.org>" imported gpg: Total number processed: 1 gpg: imported: 1 (RSA: 1)
And I still get the same message :
sudo dpkg-reconfigure pepperflashplugin-nonfree ERROR: failed to retrieve status information from google : W: There is no public key available for the following key IDs: 1397BC53640DB551 More information might be available at: http://wiki.debian.org/PepperFlashPlayer
Can you help ?
