Bom dia.
Pessoal,
Atentei no fórum que há alguns problemas parecidos com o meu, mas, por alguns detalhes não são iguais, por isso estou abrindo este novo tópico.
A mensagem de erro é a seguinte: "Um erro ocorreu, por favor, use o Gerenciador de Pacotes a partir do menu terminal para ver o que está errado. A mensagem do erro foi: "Erro desconhecido: '<class'SystemError'>'(E:MalFormed line 55 in source list /etc/apt/sources.list(dist parse))'. Isso geralmente significa que os pacotes instalados possuem dependências não resolvidas."
Segue arquivo sources.
