Updating

Agent updates provide fixes, security patches, and platform compatibility changes. The standard update path updates an existing agent to the latest published version.

Use manual updates only when you need to download a specific agent version or when Mutexer Support instructs you to use a version-specific artifact.

Update methods

Method	Use case
Cloud update	Starts an update from the device Agent page in the Mutexer Cloud Portal. Requires agent 1.0.24 or later. For more information, see Cloud updates.
Latest update	Updates an existing agent to the latest published version. For more information, see Manual updates.
Version-specific update	Downloads a specific agent version from the Agent Releases page. For more information, see Manual updates.
Integrity verification	Validates a downloaded agent against the published checksum. For more information, see Verifying Integrity.

View available versions

The Agent Releases page lists every published agent build:

https://www.mutexer.com/agent-versions

The main release list includes:

Field	Description
Version	The agent version, such as 0.0.153.
Release date	The date the version was published.
Update	Whether the update is required or optional.
Summary	A short description of the release.

Select a version to open its release page. Version-specific pages use hyphens in the URL. For example, version 0.0.153 is available at:

https://www.mutexer.com/agent-versions/0-0-153

Each version-specific release page includes the version number, release date, update requirement, reboot requirement, supported architectures, release notes, revision history, and published checksums.

Check the installed version

You can check the installed agent version in the Mutexer Cloud Portal or from the device command line.

Check the version in the portal

Open the agent configuration for the device:

Devices > Your Device > Agent

The Agent page shows the installed agent version. It also indicates when the installed version is out of date. For more information, see Agent Settings.

Check the version from the command line

Connect to the device terminal and change to the agent directory:

cd /opt/mutexer/agent

Run the agent version command:

sudo ./agent version

Review release details

Before updating, review the version-specific release page.

The page includes:

Section	Description

Artifact checksums	MD5 and SHA-256 values for each architecture.
Installation instructions	The latest update command and install guidance.
Revision history	Nearby versions in the agent release sequence.

If a release requires a reboot, schedule the update during a maintenance window.
