*(Include the actual content of the GPG key here.)*

### Explanation of Changes:
1. **Spec File Modifications**:
   - Added `Source3`, `Source4`, `Source5`, and `Source6` to include the GPG key files.
   - Updated the `%install` section to copy the GPG key files into the build root at `/usr/lib/rpm/gnupg/keys`.

2. **Added Missing GPG Key Files**:
   - Included placeholder files for the GPG keys (`gpg-pubkey-*.asc`). These files should contain the actual GPG public key content.

3. **BuildRequires and Requires**:
   - Added `gnupg2` to both `BuildRequires` and `Requires` to ensure the necessary tools for handling GPG keys are available.

These changes ensure that the symbolic links created during the build process point to valid GPG key files, resolving the build failure.
