OCORREU UM ERRO (LINUX MINT 18.1 SERENA) [RESOLVIDO]

Preciso de um help. No "gerenciador de atualizações", quando eu mando atualizar, após o "baixando informações do pacote", surge a seguinte mensagem de erro em uma caixa de diálogo próprio:

Quem puder ajudar, agradeço. A versão que estou usando é a Linux Mint 18.1 Serena. Estou acessando como super-usuário.
Obrigado

Mostre a saída desse comando:
egrep -v "^($|#)" /etc/apt/sources.list /etc/apt/sources.list.d/*

-vá em fontes de aplicativos depois em repositórios oficiais e clique em restaurar configurações originais
-ainda em fontes de aplicativos vá em repositórios adicionais e remova fonte do "precise - ubuntu-12.04)
-tente atualizar novamente
