That looks like you are trying to install an older version of libc6-dev
which is incompatible with the current version of libc6 that you have
already installed (and which cannot be removed since a lot of programs
depend on it). Please post the output of the following two commands:
apt-cache policy libc6
apt-cache policy libc6-dev
