# Updates

**Warning:** If the Collector becomes too out-of-date SIFF will block access. This is due to the collector no longer being compatible with the SIFF platform.

#### Admin > Collectors

Use the Admin module to view the set of known Collectors and their current status.

![Collector Status](https://docs.siff.io/install/collector/collector-status-errors.png)

1. Collectors that are *online* with a red version are not current but still compatible and allowed to connect.
2. Collectors in *error* with a Detail of *Collector must be updated* are not permitted to connect as they are no longer compatible.

In both cases it is recommended to update the collector.

#### Linux

Linux collectors will automatically update if outbound access to SIFF is permitted as covered in [System Requirements](https://docs.siff.io/install/system-requirements#network-access-and-ports) (see *SIFF auto-updates*)

If the system package manager is configured to automatically update packages, and outbound access is permitted as mentioned above, then this will also update the Collector on a regular basis.

For restricted systems that do not have appropriate outbound access then updates will have to be done manually, see below.

#### Forcing an update <a href="#forcing-an-update" id="forcing-an-update"></a>

1. Systems with outbound access:
   1. via the UI: use the Admin app, select the collector, and select the *Check for Updates* button.
   2. via the command line using the system package manager:
      * for **yum** (rpm): `sudo yum update siff-collector`
      * for **apt** (deb):
        1. update package list: `sudo apt update`
        2. update collector: `sudo apt install --only-upgrade siff-collector`
2. Systems without outbound access for packages or auto-updates: Follow the [Installation](https://docs.siff.io/install/collector#linux) instructions to fetch the latest version and update manually.

#### Windows / MacOS

Currently there is no auto-update feature for Windows, follow the [Installation](https://docs.siff.io/install/collector#windows) instructions to fetch the latest version and update manually.
