1, after adding users (WUWH) to Linux, "Could not update iceauthority file/home/user/" appears at logon. Iceauthority "

2, tried a lot of ways online

sudo chmod 644/home/user/. Iceauthority

For example ②, first in the login interface, the user entered the password where, press CTRL+ALT+F1
Enter the post Su to root, then adduser the username and set the password
Then reboot, after restarting, found that the newly created user, enter the password and then Su re-su failed the user name and enter the password.
Enter after the/home/fault username/next Delete. iceauthorit* all files associated with it, and then mv/home/the new username/. Iceauthority $PWD
#chown failed user name: Failed user name. Iceauthority
#chmod 644. Iceauthority
This completes the logout.
Re-select the original failure of the user, enter the password can be normal access to GNOME
After normal, you can enter #userdel new user name under terminal to delete this user

3, the ultimate solution

sudo chown user-r/home/user(problem solved after execution)

4, maybe you're still not resolved (set user to the root group)

Modify the/etc/sudoers file, find the following line, remove the previous comment (#)
# # allows people in group wheel to run all commands
%wheel all= (All) all
Then modify the user to belong to the root group (wheel),
Usermod-g Root User
