PPA não funciona

Enviado em 17/06/2014 - 20:45h

Comprei um Samsung Ativ que veio com Windows 8. Depois de muita lapada, zerei todo o HD, retirei o secure boot e demais frescuras na bios e instalei o Ubuntu 14.04 utlizando o LVM. Depois de mais algumas lapadas, consegui fazer quase tudo funcionar.

O problema é que sempre que vou adicionar um PPA aparece uma mensagem "Cannot add ppa" e pergunta se o nome que coloquei está correto. Procurei no google e achei 2 maneiras de tentar resolver o problema: ou reinstalando os certificados, ou utilizando a flag -E ao adicionar o ppa. Nenhuma funcionou. Alguém pode me ajudar?

Obrigado.

Vamos fazer um teste. Acrescente o PPA do tema de ícones Faenza, apenas um teste, depois removeremos se quiser.
No terminal:

sudo add-apt-repository ppa:tiheum/equinox

Vai pedir sua senha de root e permissão para instalar.
Permita, copie e cole todo o resultado.

Se der certo, vai importar a chave de autenticação e instalar o repositório em etc/apt/sources.list

Meu terminal:

[sudo] password for embat:
Cannot add PPA: 'ppa:tiheum/equinox'.
Please check that the PPA name or format is correct.

E agora usando a flag -E no sudo:


embat@spock:~$ sudo -E add-apt-repository ppa:tiheum/equinox

Para isso: sudo gedit /etc/apt/sources.list
Depois de deletar, copie e cole este meu acima.
Salve e feche o GEdit

Depois:
sudo apt-get update
sudo apt-get install --reinstall ca-certificates

E reaplique o comando para inserir o PPA.

O mirror é porque coloquei a opção de pegar o servidor com menos lag. Voltei pro main server e tirei tudo e continua dando erro. O do cd-rom está comentado, mas vou colar o teu e volto aqui.
