• Checking installed package integrity on Debian and Ubuntu with debsums and dpkg --verify

  debsums compares installed files against the MD5 sums recorded at package build time, dpkg --verify (since dpkg 1.17.2) compares metadata recorded in the dpkg database itself, and dpkg -S/-L answer "which package owns this file" and "what files did this package install" before deciding whether to reinstall it.

• Running apt and dpkg non-interactively on Debian and Ubuntu without hanging on prompts

  A scripted apt-get or dpkg run can stall on a debconf prompt, a modified-conffile question or a held dpkg lock. Setting DEBIAN_FRONTEND, the right confold/confdef options and preseeding debconf answers first turns an install into a command that either finishes or fails loudly.
