Failed to install Ubuntu-desktop,xshell connection in Vaware

First confirm that virtual Ubuntu can be connected properly

Probably because the OpenSSH service is not installed

sudo apt-get Install Openssh-server

Xshell the connection again, there is a problem

Cause: Ubuntu does not allow the root user to log in remotely with a password

Workaround: Log in with a non-root user, or

Modify Vim/etc/ssh/sshd_config

Find # Authentication:
Logingracetime 120
Permitrootlogin without passwd
Strictmodes Yes

Change into
