Debiean-heads might find it interesting that Joey Hess has produced a detailed SecureApt article on how to use security features of apt-get.

The particularly interesting bits are:

  • details about the security levels put into packages
  • examples of how apt-key aught to be used
  • timeline that the debian pgp keys will adhere to
  • problems to be avoided and symptoms you will see if you have ’em
  • links to relevant documentation
