I don't know if this has been discussed before, or maybe even solved before, so I thought I'd ask here before filing a feature request in the BTS.
I'd like to see apt able to check a mirror to see how 'fresh' it is. My initial concept was something like this: ------------------------------------------------------------------- Expand the "Releases" file to include a version number of some kind Add a new kind of deb line to sources.list that says where to get the authoritative version of Releases "deb-chk http://central.repostory /location" When apt-get update is run, warn about sources that have a stale Releases version ------------------------------------------------------------------- Is this something that might be possible? Am I just missing something that might already be implemented?
