After cache restore, dpkg had no record of the installed packages because: 1. Only preinst/postinst scripts were cached from /var/lib/dpkg/info/, missing .list, .md5sums, .conffiles, and other metadata files 2. The dpkg status database (/var/lib/dpkg/status) was never updated This meant dpkg -s, apt list --installed, and anything checking package state would not see the restored packages. Fix: - Cache all /var/lib/dpkg/info/<package>.* files (not just install scripts) - Save each package's dpkg status entry to a .dpkg-status file - On restore, append status entries to /var/lib/dpkg/status (skipping packages that are already registered) Adds tests verifying dpkg -s reports packages as installed after both fresh install and cache restore.
