apt package channel / python-apt
I have some interrogations about apt :
I want to develop a centralized system holding what packages operations happened on a remote debian system (in a database).
I'm using the DPkg::Pre-Install-Pkgs apt option to get information about what packages are installed/removed/updated but I need also to know from wich channel the package come (channel + url).
I have took a look at python-apt but I didn't find a good documentation :(, the same for libapt... so I've got some troubles to use it.
Thanks for your help,
