What do you want to do with the information once you got it? I ask because Debian includes some packages to do various periodic things for updates and you might be reinventing the wheel. E.g. I use apticron [1] on all the machines I manage which periodically checks if there's upgradable packages an emails me a summary of them if there are. I believe there are also means on doing other things. [1] https://debian-administration.org/article/491/Automatic_package_update_nagging_with_apticron -- Tixy
