>packages linux-libc-dev and libc6-dev (..) these are not packages in ubuntu?!
They are, but they are part of the linux and glibc source packages, respectively. Marked both these as affected now. :) When reporting bugs in the future please use apport by using 'ubuntu-bug' and the name of the package affected. That will add the report in the right place and also include additional information like version numbers automatically.
