[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.
