![]() Make sure that your reference instance is a clean installation and not in production, so that this file remains unchanged. Run ls -l /usr/bin/sudo, and then use the permissions in this example as a reference. Before you permanently set your permissions, verify the permissions from an instance with a similar operating system. Important: The permissions for /usr/bin/sudo differ across various Linux distributions. The final two command lines recover the permissions, owner, and group for the custom sudo security policy plugins in the directory /etc/sudoers.d/.

Open the Amazon EC2 console, and then select your instance.Ĭhoose Actions, Instance State, Stop. For more information, see What happens when you stop an instance. This might result in lost data, other stopped instances, and changes to the public IP address. Important: This procedure requires that you stop and start the EC2 instance. Debian-based distributions such as, Ubuntu.Red Hat-based distributions such as SUSE, CentOS, Amazon Linux 1, Amazon Linux 2, Amazon Linux 2023, and RHEL.Use a user data script to fix sudo errors on the following distributions: Note: If you receive errors when running AWS CLI commands, make sure that you're using the most recent version of the AWS CLI. For more information on configuring the EC2 serial console for Linux, see Configure access to the EC2 serial console. ![]() If you can't access your instance or the serial console, then follow the instructions in the section Method 2: Use a user data script. Also, every instance that uses the serial console must include at least one password-based user. Then, create AWS Identity and Access Management (IAM) policies that grant access to your IAM users. You can use the Amazon EC2 console or the AWS Command Line Interface (AWS CLI) to access the serial console.īefore you use the serial console, grant access to the console at the account level. The serial console connects to your instance without needing a working network connection. The serial console helps you troubleshoot boot issues, network configuration, and SSH configuration issues. If you activated EC2 serial console for Linux, then you can use it to troubleshoot supported Nitro-based instance types. To correct these errors, use the Amazon EC2 serial console or a user data script. This allows the owner and group to read the file, and it forbids anyone from writing to the file. By default, the file mode for the sudoers file is 0440. If a file is world-writable, then everyone can write to the file. The sudoers file can't be world-writable. This error occurs when the /etc/sudoers file has the incorrect permissions. The error "sudo: /etc/sudoers is world writable".The /usr/bin/sudo file must have root:root as the owner. This error occurs when a non-root user owns the /usr/bin/sudo file. "/usr/bin/sudo must be owned by uid 0 and have the setuid bit set". ![]() ![]() The following error might occur when you try to run sudo commands on an Amazon EC2 Linux instance: ![]()
