Question details
Users are experiencing an issue where a custom SPPKG package uploads to the SharePoint Online app catalog but fails to deploy.
- Product
- SharePoint Online
- Device & OS
- not provided
- Scenario
- Uploading a custom SPPKG package to a SharePoint Online app catalog for site deployment.
- Observed behavior
- The file upload completes successfully, but the deployment dialog never appears, and the Deployment column status remains set to No.
Ensure you have site collection administrator privileges or app catalog administrator rights before attempting to troubleshoot package deployments.
Isolate Browser and Permission Issues
Determine if the issue is tied to your specific browser cache or admin account permissions by testing alternative scenarios.
Because the package is known to work in other tenants, the failure to trigger the deployment dialog is likely related to localized browser cache, specific admin account session glitches, or the current app catalog environment.
Open your web browser settings, clear the cache and cookies, or open a new Incognito/InPrivate window to eliminate corrupted session data. Log back into SharePoint Online.
Ask another SharePoint administrator to log into the tenant and attempt to upload the exact same SPPKG file to see if the deployment dialog triggers for them.
Try uploading a completely different, known-working SPPKG file to your app catalog. If the dialog appears for the test package, the issue is specific to the original package's configuration in this specific tenant.
Deploy the SPPKG via PnP PowerShell
Bypass the web interface entirely by using PowerShell to add and deploy the package, which avoids browser-related UI glitches.
Try WPS Office for Seamless Document Management
While troubleshooting SharePoint and Microsoft environments can be complex, handling your daily documents shouldn't be. WPS Office offers a lightweight, highly compatible alternative to Microsoft Office, ensuring your word processing, spreadsheets, and presentations are always accessible without deployment hassles.
- 1. Download the installer: Visit the official WPS website and download the free installation package for your operating system.
- 2. Install WPS Office: Run the downloaded file and follow the quick on-screen instructions to complete the setup.
- 3. Open and edit your files: Launch WPS Office and directly open your existing Microsoft Office documents without any formatting loss.
Frequently Asked Questions
Why does my SPPKG file say 'Deployment: No'?
This occurs when the file is uploaded to the app catalog but the deployment process hasn't been triggered or completed. It is often caused by browser cache issues, insufficient admin permissions, or an unresponsive app catalog UI.
Does an SPPKG package need tenant-wide admin approval?
If the package requires specific Web API permissions (such as Microsoft Graph access), it will prompt for admin consent during deployment. If this prompt fails to load due to browser blocks, the deployment cannot be completed.
How long does it take for an app catalog to update after upload?
Typically, the deployment dialog should appear immediately after the upload completes. If it does not appear within a few seconds, refreshing the page or clearing the cache is recommended.
