Poderia ser mais especifico?

"Simplesmente porque esse "freshlight" não existe, ou já era...

coloque este símbolo # no começo da linha."

não como e onde fazer ,ficou muito vago por eu ser um iniciante.

Boa tarde,

No terminal, digite:

sudo gedit /etc/apt/sources.list

Depois procure a linha com este "freshlight" e coloque o símbolo antes da linha #. Veja na própria sources outras linhas que já estão assim, faça igual. Salve e saia. NÃO ALTERE MAIS NADA.

De volta no terminal:

sudo apt-get update

Fim....

Não encontrei.

vaje ai.
