## Update procedure

To update your installation, perform the following procedure on the Edge nodes:

1. On all Edge nodes:

   1. Clean Yum repos:

      ```
      sudo yum clean all
      ```
   2. Download the latest Edge 4.18.05 `bootstrap_4.18.05.sh` file to `/tmp/bootstrap_4.18.05.sh`:

      ```
      curl https://software.apigee.com/bootstrap_4.18.05.sh -o /tmp/bootstrap_4.18.05.sh
      ```
   3. Install the Edge 4.18.05 `apigee-service` utility and dependencies:

      ```
      sudo bash /tmp/bootstrap_4.18.05.sh apigeeuser=uName apigeepassword=pWord
      ```

      Where <var translate="no">uName:pWord</var> are the username and password you received from Apigee.
      If you omit <var translate="no">pWord</var>, you will be prompted to enter it.
   4. Update the `apigee-setup` utility:

      ```
      sudo /opt/apigee/apigee-service/bin/apigee-service apigee-setup update
      ```
   5. Use the `source` command to execute the `apigee-service.sh` script:

      ```
      source /etc/profile.d/apigee-service.sh
      ```
2. Run the `update` script on each node:

   ```
   /opt/apigee/apigee-setup/bin/update.sh -c edge -f config_file
   ```

   Where <var translate="no">config_file</var> is the configuration file that you used to install Edge for the
   Private Cloud. The only requirement is that the configuration file must be accessible
   by the "apigee" user.

## Bugs fixed

The following table lists the bugs fixed in this release:

| Issue ID | Description | Build Number^\*^ |
|---|---|---|
| 79684642 | **Invoke db_upgrade from setup** | `apigee-postgresql-9.6.1-0.0.2007` |

### ^\*^About the build numbers

> [!NOTE]
> The **Build Number** column in the table specifies the earliest version of the component that contains the fix. Use that build number to determine if you already have the fix installed, or if you need to perform an update.
>
> To find out the build number of a currently installed component, use the
> `apigee-service` utility with the following syntax:
>
> ```
> /opt/apigee/apigee-service/bin/apigee-service component version
> ```
>
> Where <var translate="no">component</var> is the name of the component without the build number extension.
> For example:
>
> ```
> /opt/apigee/apigee-service/bin/apigee-service apigee-setup version
> ```
>
> You can get the build number of *all components* with the `apigee-all`
> utility:
>
> ```
> /opt/apigee/apigee-service/bin/apigee-all version
> ```
