The error message you provided indicates that there is an issue with the fs.proc_super_gid option value in the /etc/sysctl.conf file. It also mentions that the admin user does not appear to belong to the clsudoer group.

Let's address this step by step:

1. Fixing fs.proc_super_gid in /etc/sysctl.conf:

   • Open the /etc/sysctl.conf file using a text editor. For example:

• sudo nano /etc/sysctl.conf

• Locate the line that sets fs.proc_super_gid. It might look something like this:

  php
• fs.proc_super_gid = <some_value>

• Ensure that the value is set correctly. If you're not sure what value to use, you might need to consult your system's documentation or the provider's instructions.

• After making any changes, save the file and exit the text editor.

• Apply the changes using the following command:

  • sudo sysctl -p

• Adding Admin User to clsudoer Group:

  • If the admin user needs sudo privileges, you should add them to the sudo or wheel group, not clsudoer.

  • To add a user to the sudo group, use the following command, replacing <username> with the actual username:

2. • sudo usermod -aG sudo <username>

   • After adding the user to the sudo group, they will have sudo privileges.

3. Reboot:

   • After making these changes, it's a good idea to reboot your system to ensure that all changes take effect.

Remember, always be cautious when editing system configuration files, and make sure to have backups or a way to access your system in case any changes cause issues. If you're unsure about any specific configurations, it's a good idea to consult the documentation for your specific system or seek advice from a qualified system administrator.
