Acabei de ter o mesmo problema quando tentei instalar os drivers gráficos da Intel.
A solução é remover /etc/apt/sources.list.d/intellinuxgraphics.list
ou comentar.
Depois de ter feito isso, basta executar sudo apt-get -f install
para corrigir as dependências quebradas.
Embora, não me peça para explicar o que deu errado (faltando o conhecimento para descobrir o porquê). Mas meu palpite é que a Intel estragou algo.

Também esqueci de mencionar que foi causado usando o Intel Linux Graphics Installer em primeiro lugar.
