Plesk Support SSH Access extension provides error: Binary sa-visudo.sh execution failed: visudo: invalid option -- 'x' usage

Symptoms

• Plesk Obsidian running on a Linux-based operating system
• The Support SSH Access extension for Plesk provides error that is similar to the following on an attempt to provide server access:

PLESK_ERROR: Failed to provide access: Extracting JSON from visudo failed: Binary sa-visudo.sh execution failed with error code 1; stdout [] stderr [visudo: invalid option -- 'x' usage: visudo [-chqsV] [-f sudoers] ]

Cause

An outdated sudo package installed on the server and it prevents the extension from functioning as expected.

Resolution

Update the sudo package by following these steps:

1. Log into your server via SSH as the root user

2. Update using one of the following commands (depending on the type of operating system you are using):

For a RHEL-based operating system:

# yum install sudo -y

For a Debian-based operating system

# apt update && apt install sudo -y

Once this is done, you would be able to provide server access via the Support SSH Access extension for Plesk normally
