What is Rsync?

Rsync was initially built as a basic clone of “rcp” (Remote Copy) but with a handful of additional features. That handful of additional features has expanded over the years and made Rsync an indispensable tool. This simple tool can be used to copy files between directories on a local computer. Or you can use it to copy files to and from remote systems.

So How do I Use Rsync?

The basic command is pretty simple, rsync [options] [source] [destination], and in this simple form you can easily copy data between local directories. ie: rsync /home/bdoga/source/file /home/bdoga/destination/ This command will take “file” and place it inside the “/home/bdoga/destination/” directory.

What is the NO_PUBKEY error?

The APT NO_PUBKEY error shows up when the public/private key pair has changed for one of your APT repositories. When this happens, if your local system or server does not have the correct public key, then it cannot verify the repository. And therefore you get the error. This process is in place to ensure you don’t accidentally download packages from an unknown APT source.
