# Why is NextSeq 1000/2000 control software update not available from the Software Update menu?

**Background:**

Regularly updating the NextSeq 1000/2000 Control Software suite (NCS) ensures the system has the latest features and fixes. Software updates are bundled into a system suite, which includes the following software:

* NextSeq 1000/2000 control software
* NextSeq 1000/2000 recipes
* Universal Copy Service
* Real-Time Analysis

The system can be configured to download updates automatically or manually.

* **Automatic Updates** - Updates are automatically downloaded from BaseSpace Sequence Hub to install. This option requires an internet connection, but not a BaseSpace Sequence Hub account.
* **Manual Updates** - Updates are manually downloaded from the web, saved locally or to a portable drive, and installed from the saved location. This option does not require an internet connection for the instrument.

**Enabling/Disabling Automatic Updates:**

To enable/disable Automatic Updates - configure the Software Updates from the control software's **Settings** menu.

1. From the control software menu, select **Settings**.
2. Choose whether the system checks for software updates automatically:
   * To check automatically, **select** the **Autocheck for software updates** checkbox.
   * To check manually, **deselect** the **Autocheck for software updates** checkbox.
3. Select **Save**.

**The Software update notification does not appear:**

Only systems configured for automatic updates display an alert when a software update is available. If an alert is not displayed one of the following may apply.

* System is operating under the most recent version of control software and no update is available. Verify against the [NextSeq 1000/2000 Software Downloads](https://support.illumina.com/sequencing/sequencing_instruments/nextseq-1000-2000/downloads.html) page for the most current version of control software available.
* The system is not connected to the internet, verify internet connection and try again. In certain cases, the network firewall may need adjusting to allow connections to the BaseSpace servers for update checks. See the [Illumina Product Security](https://support.illumina.com/product-security-portal.html) site for more information.
* `If currently logged in as ilmnadmin and update is not visible, verify ilmnadmin` password is not expired. Updates to the control software must be completed from the `ilmnadmin` account. This password requires update every 180 days, when prompted. If the `ilmnadmin` password is expired, the automatic download of the updated software suite cannot be completed. Update the `ilmnadmin` credential and retry. For more information, see [How to Reset Linux Operating System (OS) User Passwords on the NextSeq 1000/2000](/instrumentation/nextseq-1000-2000/instrumentation-nextseq-1000-2000-troubleshooting-list/000003297.md)

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://knowledge.illumina.com/instrumentation/nextseq-1000-2000/instrumentation-nextseq-1000-2000-troubleshooting-list/000007335.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
