Eu adicionei um repositório à lista de fontes para um pacote de uma versão mais recente do Ubuntu. Então eu instalei o pacote, com vários outros pacotes requeridos. Isso quebrou o sistema de pacotes: não consigo instalar atualizações ou executar o Kate, por exemplo. Como consertar isso?
Abaixo está a saída de apt-get -f install .
