Unable to install CloudLinux due to the "You have users in the group 'clsudoers', 'clsupergid' or both." error

Issue

There is the following error during the cldeploy script working:

You have users in the group 'clsudoers', 'clsupergid' or both.
This may create a security issue on the server, because after the conversion
the users in those groups will be granted permissions higher than of a simple user.
Please move the users to another group(s).

Environment

• CloudLinux 7/Hybrid
• Any control panel

Solution

1. Check the /etc/group file for users in the groups clsupergid and clsudoers:

egrep 'clsudoers|clsupergid' /etc/group

Example of the output:

# egrep 'clsudoers|clsupergid' /etc/group
clsupergid:x:1000:root,mailman,polkitd
clsudoers:x:1001:root

2. Remove users from the groups. In this case, they are root, mailman, polkitd:

# gpasswd -d mailman clsupergid
Removing user mailman from group clsupergid
# gpasswd -d polkitd clsupergid
Removing user polkitd from group clsupergid
# gpasswd -d root clsupergid
Removing user root from group clsupergid
# gpasswd -d root clsudoers
Removing user root from group clsudoers

3. Run the cldeploy script again.

You may run:

# wget https://repo.cloudlinux.com/cloudlinux/sources/cln/cldeploy
# sh cldeploy -i --skip-registration

Cause

The users were added to the groups clsupergid and clsudoers before CloudLinux installation. It happens when you had CloudLinux on your server before and install it again.
