How to revoke sudo access?

To revoke sudo access from a user, you can remove them from the sudo group. Here’s how to do it:

1. Open a terminal.

2. Use the following command to remove the user (replace username with the actual username) from the sudo group:

   sudo deluser username sudo
   

3. To verify that the user has been removed from the sudo group, you can check the groups associated with the user:

   groups username
   

The output should no longer include the sudo group, indicating that the user no longer has sudo access.
