Most software repositories use a GPG key to digitally sign the files they provide, which makes it easy to check that the files have not been tampered with since their creation. In order for apt to be able to check this, you need the public key that corresponds to the signatures. The key should be available for download on the repository's website.

Other than using tools that download packages automatically, it is also possible to use a CD to install packages through a package manager while not connected to the Internet. The Ubuntu installation CD can be used for this purpose, and other CDs with different packages are available as well. Additionally, the program <application>APTonCD</application> can automatically backup installed packages on your system, and create CDs with the contents of various repositories on them.
