Error while restoring cPanel backup

Error :

Sorry, a group for that username already exists.

Fix :

User account related information is stored in /etc/passwd, /etc/shadow and /etc/group files . Check all of them and remove the entries.

You can remove the group by using:

groupdel groupname

And then restore the account.

You can also restore the account forcefully by using :

/scripts/restorepkg –force username
