Recovery of Ubuntu User File loss

In the Ubuntu environment, when deleting a common file, the user folder under/home is deleted without a clear prompt. The first response is that all shortcuts in the menu are invalid, because the original links are in the/home/usrname directory. If the directory does not exist, all shortcuts of the day are invalid, restart, enter the user name and account, and the system prompts "user's $ home /. dmrc has been ignored, so the default session and language cannot be saved. The file should be owned by the user and the permission is set

"The user's $ home/. dmrc has been ignored, so the default session and language cannot be saved. The file should be owned by the user and the permission should be set to 644. The $ home directory of the user should be owned by the user, and other users cannot write data ."

Despite knowing the root account, the system does not allow direct root login in window mode,

So, restart again,

When you are prompted to enter the recovery mode, click "esc ",

Go to the menu options and enter the recovery mode. There are many options. You can enter the top recovery mode,

The system prompts you to enter the root account. If you do not have a root account, you can follow the prompts to perform the operation,

Check that the/home directory does not have a user directory,

Create useradd usrname,

Prompt that the user exists. It seems that the user skill exists, but the directory is gone,

Therefore, create a user directory

Sudo mkdir/home/usrname

Give the user owner and group information,

Sudo chown-R usrname: usrname/home/usrname

(The user name and the specific name of the user group must be determined based on the actual situation)
