Inicialmente, recebi o seguinte erro:

Isso parece um monte de pacotes para remover, e alguns desses [ xorg , xserver-xorg-core-lts-utupic ] soam como uma coisa SUPER-arriscada para concordar.
Por que está tentando desinstalar meus pacotes HWE? Isso é uma dependência quebrada com libsdl2-dev ?
Adicionando muito os pacotes do Utopic. Eles fazem parte do Hardware Enablement Stack e constituem atualizações importantes que normalmente não são feitas. Veja Kernel / LTSEnablementStack - Wiki do Ubuntu
De acordo com Como atualizar o Ubuntu 12.04.2, 12.04.3 para 12.04.4, a próxima pilha de ativação de hardware? - Pergunte ao Ubuntu
você deve incluir --install-recommends ao fazer essas atualizações importantes.
