2. Edit the source list file

sudo vim/etc/apt/source.list

3, the original list is deleted, add the following (replace the image of Ali, you can also change the other)

Deb Http://mirrors.aliyun.com/ubuntu/vivid main restricted universe multiverse
Deb Http://mirrors.aliyun.com/ubuntu/vivid-security main restricted universe multiverse
Deb Http://mirrors.aliyun.com/ubuntu/vivid-updates main restricted universe multiverse
Deb http://mirrors.aliyun.com/ubuntu/vivid-proposed main restricted universe multiverse
Deb Http://mirrors.aliyun.com/ubuntu/vivid-backports main restricted universe multiverse
DEB-SRC Http://mirrors.aliyun.com/ubuntu/vivid main restricted universe multiverse
DEB-SRC http://mirrors.aliyun.com/ubuntu/vivid-security main restricted universe multiverse
DEB-SRC http://mirrors.aliyun.com/ubuntu/vivid-updates main restricted universe multiverse
DEB-SRC http://mirrors.aliyun.com/ubuntu/vivid-proposed main restricted universe multiverse
DEB-SRC http://mirrors.aliyun.com/ubuntu/vivid-backports main restricted universe multiverse

4. Run sudo apt-get update

5. Run sudo apt-get upgrade

Second, install SSH, configure SSH login without password

1. sudo apt-get install openssh-server
2. SSH localhost
3. Enter Yes to enter the password for the current account

4. Exit # quit the ssh localhost just now
   CD ~/.ssh/# If you do not have this directory, first execute SSH localhost once
   SSH-KEYGEN-T RSA # will be prompted, press ENTER to
   Cat./id_rsa.pub >>./authorized_keys # Join License

This will allow you to login without a password.
