+apt repositories' keyrings
+==========================
+
+Debian family of OSes deprecated the use of `apt-key` to manage repositories' keys
+in favor of using `keyring files` which contain a binary OpenPGP format of the key
+(also known as "GPG key public ring")
+
+As arvados don't provide such key files, we created it pulling the
+official key from its site and install the resulting file.
+
+See https://doc.arvados.org/main/install/packages.html#debian for details
