--- Comment #1 from Darren Tucker <dtucker at dtucker.net> ---
DSA support was removed in 10.0.  From the first item of the first
section of the release notes
(https://www.openssh.com/releasenotes.html#10.0).

Potentially-incompatible changes
--------------------------------

 * This release removes support for the weak DSA signature
   algorithm, completing the deprecation process that began in
   2015 (when DSA was disabled by default) and repeatedly warned
   over the last 12 months.

> I require HOSTKEYALGORITHMS=+ssh-dss for peripherals.

Then your options are:
1) Use 9.9p1 or 9.9p2 configured with --enable-dsa-keys.
2) Use 9.8 or earlier.
3) Consider upgrading whatever the clients are that don't support
anything better than DSA.
