have When trying a passwordless connection via ssh, I have now the message:

According to the buster manpage of sshd_config:

PubkeyAcceptedKeyTypes
Specifies the key types that will be accepted for public key authentication as a list of comma-separated patterns. Alternately if the specified value begins with a ‘+’ character, then the specified key types will be appended to the default set instead of replacing them. If the specified value begins with a ‘-’ character, then the specified key types (including wildcards) will be removed from the default set instead of re‐
      placing them. The default for this option is:

          ecdsa-sha2-nistp256-cert-...@openssh.com,
          ecdsa-sha2-nistp384-cert-...@openssh.com,
          ecdsa-sha2-nistp521-cert-...@openssh.com,
          ssh-ed25519-cert-...@openssh.com,
          rsa-sha2-512-cert-...@openssh.com,rsa-sha2-256-cert-...@openssh.com,
          ssh-rsa-cert-...@openssh.com,
          ecdsa-sha2-nistp256,ecdsa-sha2-nistp384,ecdsa-sha2-nistp521,
          ssh-ed25519,rsa-sha2-512,rsa-sha2-256,ssh-rsa

      The list of available key types may also be obtained using "ssh -Q key".


So there is nothing for dsa, only ecdsa.

The default list in stretch is shorter but doesn’t have a dsa type either.

Shade and sweet water!
