Cannot remove account with error - You do not have a user named “user”

Symptoms

When trying to remove an account, you get the error:

You do not have a user named “user”

Description 

If the account is partially removed and has data in /var/cpanel/userdata/ missing, the account cannot be removed/terminated.

Workaround

 The cPanel account's userdata folder needs to be created, and the group needs to be set. In the following steps, replace "$username" with the username you're trying to remove.

1. Create the userdata directory:

   mkdir /var/cpanel/userdata/$username

2. Change the group of the directory to match the user:

   chgrp $username /var/cpanel/userdata/$username

3. Set the proper permissions for the directory:

   chmod 750 /var/cpanel/userdata/$username
