I changed the mirror, now apt-get update workd fine. After reading https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=389894 I suspect an issue with the server itself.
** Bug watch added: Debian Bug tracker #389894 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=389894 -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to apt in Ubuntu. https://bugs.launchpad.net/bugs/1027801 Title: Packages.gz not found because instead searching for Packages only Status in “apt” package in Ubuntu: Confirmed Bug description: apt-get update gives a warning (not only apt-get: synaptic or all other packet managing tools too): W: Failed to fetch http://de.archive.ubuntu.com/ubuntu/dists/precise/multiverse/binary- amd64/Packages 404 Not Found [IP: 141.30.13.20 80] This warning is ok, since "Packages" doesn't exist at "http://de.archive.ubuntu.com/ubuntu/dists/precise/multiverse/binary- amd64/". "Packages.gz" (or Packages.bz2) do exist indeed. Two possibilities: 1. The string "http://de.archive.ubuntu.com/ubuntu/dists/precise/multiverse/binary-amd64/Packages.gz" is exactly 3 characters to long for the defined buffer, thus shortened by ".gz". 2. The Repository isn't correctly initialized, stating "Packages" instead of "Packages.gz" or "Packages.bz2" to load. Since all other repositories are loaded and look the same (and defining a new repository holding the very same files than this ony, but with a shorter path makes it load) I am tending to the first possibility ...
