Further diagnosis shows that this is only a problem when fetching files via an ‘apt-cacher’ instance. It occurs for any requested files; ‘Packages.gz’ or binary ‘….deb’ have both shown this behaviour. ===== $ sudo aptitude full-upgrade Reading package lists...

Estimated time to complete varies during the process, but is on the order of 10 hours. I can only interrupt the process, or it will cycle indefinitely. The ‘/var/log/apt-cacher/*.log’ files show no unusual behaviour; only accesses of the requested files. When I reconfigure ‘/etc/apt/sources.list.d/’ to avoid the ‘apt-cacher’ proxy, the download proceeds much faster and downloads files only once as expected: ===== $ sudo aptitude update && sudo aptitude full-upgrade Get:1 http://security.debian.org lenny/updates Release.gpg [189B] Ign http://security.debian.org lenny/updates/main Translation-en_AU Get:2 http://security.debian.org lenny/updates Release [40.7kB] Get:3 http://mirror.internode.on.net lenny Release.gpg [189B] Ign http://mirror.internode.on.net lenny/main Translation-en_AU Hit http://volatile.debian.net lenny/volatile Release.gpg Ign http://volatile.debian.net lenny/volatile/main Translation-en_AU Hit http://volatile.debian.net lenny/volatile Release Ign http://volatile.debian.net lenny/volatile/main Packages/DiffIndex Get:4 http://mirror.internode.on.net lenny Release [74.5kB] Hit http://volatile.debian.net lenny/volatile/main Packages Get:5 http://security.debian.org lenny/updates/main Packages [172kB] Get:6 http://mirror.internode.on.net lenny/main Packages [5359kB] Fetched 5647kB in 9min34s (9835B/s) Reading package lists...
