When adding a repository through add-apt-repository a new gpg key will be add.
e,g:
sudo add-apt-repository ppa:some-ppa
You will be asked to press Enter to import the gpg key. I need to get the gpg key for ppa:some-ppa without executing add-apt-repository.
Is it possible to get the gpg key before adding the repository (before executing add-apt-repository) from command line?
