Hello there, this error is unfortunately very unhelpful. It can mean that you have some other package which explicitly conflicts with something apt-get is trying to install (e.g. if you have some kind of BLAS library that says it conflicts with openblas, ATLAS and libblas for instance), or it could mean that you have some package that is in a weird not-installed yet not-uninstalled state. Please read through this SO answer<http://askubuntu.com/questions/223237/unable-to-correct-problems-you-have-held-broken-packages>, try out their solutions (in particular `apt-get install -f julia`, `dpkg --configure -a` and `sudo aptitude install julia`) and let us know what those solutions come up with.
