My package is not updating automatically

Cause

Your installation may not be updating automatically for any of the following reasons:

The Update Strategy is set to Manual instead of Automatic.
A specific version of the package is requested, instead of the latest version.
The client is in a deployment circle that is set to a specific version.
Client background service is not installed or not running.
Unable to resolve dependencies due to misconfiguration.
Error in the installation process.

Resolution

To resolve this problem, use any one of the following methods, depending on the cause of the problem:

Change Update Strategy:
- In 1.3 and above: Open the client app, find the package or instance, hit Options, and change the Update Strategy to Automatic.
  - Start Menu -> Update Service -> Installed Components -> Package or instance -> Options -> Change Update Strategy to Automatic.
- In 1.2.X and below, edit appropriate JSON file and set the UpdateStrategy property to Automatic.
  - C:\programdata\LS Retail\GoCurrent\Client\Installed\package-id.json"
  - C:\programdata\LS Retail\GoCurrent\Client\Installed\INSTANCENAME\package-id.json"
  - You may need to install the client service when changing the update strategy through JSON files, see below.
Change specific version to latest version
- In 1.3 and above: Open the client app, find the package or instance, hit Update, and hit Install Latest. The install latest will not appear if it is already set to the latest version.
  - Start Menu -> Update Service -> Installed Components -> Package or instance -> Update -> Install Latest.
- In 1.2.X and below: Edit the appropriate JSON file and set the VersionQuery property to an empty string.
  - NOTE: Do not add the VersionQuery property if it is not already present.
  - NOTE: If this is an instance, you may need to update multiple JSON files.
  - C:\programdata\LS Retail\GoCurrent\Client\Installed\package-id.json"
  - C:\programdata\LS Retail\GoCurrent\Client\Installed\INSTANCENAME\package-id.json"
Check if a deployment circle is configured for the target package.
- Verify if the client is in any deployment circles and if the target version for the circle is correct.
- Verify if the outermost deployment circle is set to the correct version.
To check for a dependency error, open the client app, locate the package or instance, and select Update. If a dependency error exists, an error will occur.
- Start Menu -> Update Service -> Installed Components -> Package or instance -> Update.
Check if an error occurs during the installation:
- In the server UI, go to the Installs page to see if there are any installation attempts by the client.
- Check the logs, in C:\programdata\LS Retail\GoCurrent\Client\Log, sort by date modified and search for the latest LSRetail.UpdateService.Client.Service.exe- log file.
Verify if the client background service is installed and operational:
- Open the Windows Services and check if the LS Go Client Client Service exists and running.
- If not, you can install the service via PowerShell as follows:
```
Install-UscPackage -PackageId 'go-current-client-service'
```

Note

To trigger an update immediately, restart the client service.
