[microsoft/vscode] Extension Signature Verification Failed: BLACKBOXAI Agent - Coding Copilot

GH-microsoft/vscode#299910 • Mar 07, 2026

### ROOT CAUSE The "Extension Signature Verification Failed" error typically occurs when VS Code is unable to verify the digital signature of an extension. This can happen due to several reasons: 1. The extension might not be signed. 2. The signature might be corrupted or invalid. 3. There might be a temporary issue with VS Code's signature verification process. In this case, the extension in question is the BLACKBOXAI Agent - Coding Copilot. The error could be due to an older version of the extension or a corrupted installation. ### CODE FIX To resolve this issue, follow these steps: 1. **Reinstall the Extension:** - Uninstall the BLACKBOXAI Agent - Coding Copilot extension from VS Code. - Restart VS Code. - Install the extension again from the VS Code Marketplace. 2. **Update VS Code:** - Ensure you are using the latest version of VS Code. Sometimes, updates fix underlying issues with extension verification. 3. **Disable the Extension Temporarily:** - If the issue persists, disable the BLACKBOXAI extension to rule it out as the cause of other potential issues. 4. **Contact the Extension Developer:** - If the problem continues, reach out to theBLACKBOXAI support team for further assistance.
