ciao a tutti,
sto cercando di installare clipgrab su debian 9.6 tramite ppa, ma c'è un errore su chiave gpg:

sudo add-apt-repository ppa:clipgrab-team/ppa
 This PPA contains the latest stable version of ClipGrab for LTS releases. For other versions see <https://launchpad.net/~anton+/+archive/ubuntu/photo-video-apps>
 
Requires ffmpeg. Ubuntu 14.04 only: Canonical dropped the ffmpeg package; a symlink from /usr/bin/avconv to /usr/bin/ffmpeg will be created as a workaround. 
 
Installation instructions for the terminal:
 
sudo add-apt-repository ppa:clipgrab-team/ppa
sudo apt-get update
sudo apt-get install clipgrab
 
Alternatively you can add ppa:clipgrab-team/ppa to your system's Software Sources in the Ubuntu Software-Center. If you want to upgrade your system, please remove clipgrab and clipgrab-team/ppa first.
 More info: https://launchpad.net/~clipgrab-team/+archive/ubuntu/ppa

mi rispondo da solo: prima ho caricato nel file /etc/apt/source.list i seguenti repository (per ubuntu 18.08):

#clipgrab
deb http://ppa.launchpad.net/clipgrab-team/ppa/ubuntu bionic main 
deb-src http://ppa.launchpad.net/clipgrab-team/ppa/ubuntu bionic main 

poi ho caricato le chiavi seguendo questo suggerimento:

It happens when you don't have a suitable public key for a repository.
 
To solve this problem use this command:
 
gpg --keyserver hkp://keyserver.ubuntu.com:80 --recv D8AD4DE78EEBB0CA
 
which retrieves the key from ubuntu key server. And then this:
 
gpg --export --armor D8AD4DE78EEBB0CA | sudo apt-key add -

quindi:

sudo apt-get update
sudo apt-get install clipgrab 

in questa maniera ho risolto !
