It seems that when I added the repository for MuseScore and upgraded MuseScore to 2.0, it also updated qt to 5.3 which seems to be incompatible with Makerware.

For now, it looks like I have to downgrade MuseScore or not use Makerware.

Whenever u install fresh Ubuntu , you need to update and upgrade the system to install from ubuntu repositories.

sudo apt-get update && sudo apt-get dist-upgrade

Now install anything

 sudo apt-get install mysql-server
