onde gstreamer1.0-plugins-good é o pacote que estou tentando corrigir em primeiro lugar.
Eu também acho que cheguei a dependências circulares com libtinfo , libtag* , libtag*vanilla e libncursesw5 . Por exemplo, com libtinfo :

OK, então vamos dpkg -i libtinfo5 (= 6.0+20160213-1ubuntu1) …

Portanto, libncursesw5 requer libtinfo5 (= 6.0+20161126-1) , enquanto outra biblioteca requer a versão 20160213 . Além disso, libncursesw5 não é removível porque procps depende disso, e componentes vitais do sistema que não podem serem removidos (por exemplo, xdm ) dependem de procps .

o muito antigo ( hardy ) libncursesw5_5.6+20071124-1ubuntu1_i386.deb parece o que era necessário.
dselect é mais fácil que dpkg .
Anote o comentário de @ doug de que a instalação de pacotes a partir de repos sid do Debian é uma má ideia. Os arquivos .deb precisam ter *ubuntu* no nome.
