add-key
So recently-ish debian deprecated using apt-key add - in favor of adding individual signed keys. This is all well and good but this process is a pain in the butt. So I created this simple little utility to make it easier.
The following is an example to install the spotify repo https://www.spotify.com/us/download/linux/
kellen@chewbacca:~/pkg/add-key$ sudo ./add-key spotify --gpg=https://download.spotify.com/debian/pubkey_5E3C45D7B312C643.gpg --suite=stable --components=non-free --uri=http://repository.spotify.com
Wrote /usr/share/keyrings/spotify.gpg
Wrote /etc/apt/sources.list.d/spotify.sources
