fix lỗi apt-get install trên ubuntu

vào một ngày đẹp trời bạn tư dưng không dùng apt-get install trên ubuntu được nữa. kiểm tra thì không phải là do DNS.Nguyên nhân là do các link trong file sources.list không tồn tại nữa.

đầu tiên bạn xóa hết text trong /etc/apt/sources.list

#vi /etc/apt/sources.list

sau đó dán đoạn text dưới đây vào.
