Check and modify the information in system info to make it consistent with the following content:

system_info:
   distro: sles
   default_user:
     name: root   // User name for OS login
      lock_passwd: False   // True indicates that login using a password is disabled. Note that some OSs use value 1 to disable the password login.
     gecos: redhat
groups: [adm, audio, cdrom, dialout, dip, floppy, lxd, netdev, plugdev, sudo, video]   // (Optional) Add the user to other groups that have been configured in etc/group.
      sudo: ["ALL=(ALL) NOPASSWD:ALL"]  //Current user has all the root rights.
      shell: /bin/bash   //Execute shell in bash mode.
   paths:
      cloud_dir: /var/lib/cloud/
      templates_dir: /etc/cloud/templates/

```
# to update this file, run dpkg-reconf igure cloud-init
datasource_list: [ OpenStack ]
