Oh, I thought that auto-detection of SHA1 readiness does the same thing as this explicit configuration file disabling. It does not indeed. Okay, then build-time disabled or not yet supported algorithms (like PQC) are needed. I maybe get why it slipped through untested then.

Only now I get what was meant by the comment to test different variant of this problem, with different algorithms used.

Sorry for misleading information, I did not test it on different system. I though it behaves the same in the validator.

I do not even have my Debian sid container on my new laptop (yet!).

Debian never had that problem, as RSASHA1 is not disabled there in the crypto 
library, the setting

        disable-algorithms . {
                RSASHA1;
        };

is a different.

You would need something like RSAMD5 + <supported algorithm> to reproduce the 
issue.

But I'm unable to reproduce the original issue with the current 9.20.15
based package in Debian.  Probably doing something wrong...
