apt-get update [RESOLVIDO]

Olá gente do viva o linux

Alguém pode me ajudar com este problema?

Lendo listas de pacotes... Pronto
W: Duplicate sources.list entry http://security.ubuntu.com/ubuntu/ trusty-security/main amd64 Packages (/var/lib/apt/lists/security.ubuntu.com_ubuntu_dists_trusty-security_main_binary-amd64_Packages)
W: Duplicate sources.list entry http://security.ubuntu.com/ubuntu/ trusty-security/restricted amd64 Packages (/var/lib/apt/lists/security.ubuntu.com_ubuntu_dists_trusty-security_restricted_binary-amd64_Packages)
W: Duplicate sources.list entry http://security.ubuntu.com/ubuntu/ trusty-security/main i386 Packages (/var/lib/apt/lists/security.ubuntu.com_ubuntu_dists_trusty-security_main_binary-i386_Packages)
W: Duplicate sources.list entry http://security.ubuntu.com/ubuntu/ trusty-security/restricted i386 Packages (/var/lib/apt/lists/security.ubuntu.com_ubuntu_dists_trusty-security_restricted_binary-i386_Packages)
W: Você terá que executar apt-get update para corrigir estes problemas


Claro que quando executo novamente o update o erro se repete.
Tentei editar meu sources.list porém não sei quais pacotes posso realmente remover.
Meu sistema é 64bits


Se alguém puder ajudar eu agradeço =)

sudo gedit /etc/apt/sources.list apague a linha que estiver duplicada salva fecha e de um update.Ou use o synaptic que e mais facil!

Como posso saber se as linhas são realmente duplicadas? Por exemplo, se deb e deb-src são diferentes ou posso removelos quando forem iguais...

Cola todo esse comando de uma vez e de enter:sudo rm /var/lib/apt/lists/* ; sudo rm /var/lib/apt/lists/partial/* ; sudo apt-get -f install ; sudo apt-get clean ; sudo apt-get update

sudo rm /var/lib/apt/lists/lock
sudo rm /var/lib/dpkg/lock
sudo apt-get update

rm: não foi possível remover “/var/lib/apt/lists/partial”: É um diretório
rm: não foi possível remover “/var/lib/apt/lists/partial/*”: Arquivo ou diretório não encontrado



Depois disso ele prosseguiu com o update e deu o aquele mesmo erro

O mesmo erro persistiu

Para remover diretórios use

rm -rf diretório
