Estou enfrentando problemas ao tentar atualizar minha máquina faz alguns dias. Sempre que tento aparece essa mensagem:

Já vi que alguns repositórios parecem estar duplicados mas não sei como proceder. Caso alguém possa ajudar, agradeço.

Vá em Configurações do sistema >> Programas e atualizações >> Outros programas

Desative os PPAs, deixando apenas Paceiros da canonical

Atualize o sistema: sudo apt update && sudo apt upgrade

Olá! Como corrigir esses erros via linha de comando, já que estou acessando via ssh?

Uso o Linumint 18.1 Serena e tive o mesmo problema. Consegui resolver desativando os repositórios duplicados, que se encontram no gereciador de atualizações/fontes de programas/repositórios adicionais. Bastou apenas eu desabilitar os repositórios que se encontravam duplicados, como segue na imagem:
