Now that you installed "tracker", you either should comment out "Yakkety
main universe", or use pinning,
https://help.ubuntu.com/community/PinningHowto#Examples , to avoid that
an upgrade damages your install.

Since the output of apt-cache doesn't show a line similar to

  "500 http://de.archive.ubuntu.com/[snip]"

I suspect you already commented out the repository.

This kind of backport doesn't work always.
