# Update Segura™

Keeping your Segura™ application up to the latest version ensures a more secure environment with enhancements. Refer to the **Changelog** of our latest version for details about new features, fixes, security enhancements, and usability improvements.

Caution

In order to perform the update, you have to indicate the location of the repository. For information on how to perform this action, access the [How to manage repositories with Orbit CLI](/v4-2/docs/how-to-manage-repositories-with-orbit-cli) document.

You can update your application in three ways:

- [Online update.](/v4-2/docs/installation-how-to-update-senhasegura-online)
- [Offline update](/v4-2/docs/installation-how-to-update-senhasegura-offline).
- [Updating a clustered environment](/v4-2/docs/installation-how-to-update-cluster).

## Disk space requirements

Every update checks the disk space of the appliance before it changes anything. Check these requirements before the update window:

| File system | Requirement |
| --- | --- |
| `/usr` | At least 12 GB in total. If you expand it, use 16 GB or more when possible. |
| `/var` | At least 10 GB free, to download the update packages. |
| `/usr` | At least 1 GB free, to install the packages. |

To check the size and free space, [start an SSH session as an administrator user](/v4-2/docs/administration-ssh-access) and run:

```
df -h /usr /var
```

The **Size** column shows the total size, and the **Avail** column shows the free space. A 12 GB `/usr` can show slightly less than 12G because the file system reserves part of the volume. The check accepts it.

### Appliances with a small `/usr`

Appliances installed from the 3.29.1 image have an 8 GB `/usr` partition. The partition keeps this size after later updates, so these appliances cannot update until `/usr` is expanded.

If `/usr` is smaller than 12 GB, plan the expansion before the update window. [Contact Segura™ support team](https://support.segura.security/).

### If the update does not start

If a requirement is not met, the update stops at the start and shows the reason in the terminal. Nothing is changed on the appliance. Free up space or expand the file system, then run the update again.

The message appears only in the terminal and is not saved in the update logs. Keep a copy of the command output, especially if you contact support.
