Ajude-me a corrigir dependências no sudo apt-get -f install failure

Question

Então, eu estava tendo alguns problemas com meu gerenciador de rede e tentei reinstalá-lo, pois não funcionaria.

Avance alguns pacotes mais tarde e agora o gerenciador de rede e a rede funcionam, mas não tenho nenhum ícone, no lado superior direito, com as redes. Eu tenho este ícone de erro com a mensagem erorr:

"Error: BrokenCount>0".

Seguir as instruções fornecidas não resolve o problema, pois ainda recebo o erro abaixo.

O instalador do Ubuntu Software também não funciona. Quando tento instalar / atualizar algo, ele apenas carrega um pouco e depois pára como se eu tivesse cancelado.

Se alguém pudesse resolver este, eu ficaria grato.
