ERROR Key corrupted: Could not open key: no valid primary key self-signature or key(s) have expired

Hello, I receive this error message when trying to sign the installation. My key is valid, not expired, working in all other circumstances, and self signed. It's also uploaded to pks ( EDAA1B94B4AD4482FEBE192B972C8B97E8086B4A ) I am able to log in using a browser, refreshed my public key there, so it is the most current version, but that doesn't solve the problem.

The report provides no file, test, or entry point. Start by reproducing installation signing with the referenced key and trace the key-validation path that emits “no valid primary key self-signature or key(s) have expired.” Done means identifying why this valid key is rejected and adding a verified fix or a focused regression test.
