I was wondering about that, too, and while trying to figure it out,
discovered that I hadn't noticed considerable earlier changes to apt.
Please note that my following remarks refer only to sid/unstable!
First a bit about dependencies: kde-standard depends on update-notifier-
kde which in turn depends on update-notifier-common.
Apt itself has, apparently for quite some time (years!), had the options
that trigger periodic updates of the list of available packages.
However, judging only from my own experience and the fact that I had
never heard of them, these options have not been widely used. So far,
that is. Because now update-notifier-common installs
thereby enabling automated daily updates of the package list. More
details can be found in
I have to admit that I was taken slightly aback by these changes and I'm
not yet sure whether there is anything I need to do in order to make
things work the way I want. As far as I can tell, documentation is non-
existent or just not where I looked. Well, it's called "unstable" for a
reason, after all.
