focal sshd doesn't answer VX Connectbot.  no idea why.  no problem with
bionic sshd, even if invoked on the focal kernel.  tried to simply
substitute bionic /usr/sbin/sshd into focal, wouldn't start.  works in a
bionic chroot on focal, but from there tunnels don't connect.  i submitted
a bug <https://bugs.launchpad.net/ubuntu/+source/openssh/+bug/1877496>, but
i'm not holding my breath for a resolution.

so next i thought i'd try to install the bionic openssh-server package in
focal.  perhaps can be done with dpkg, probably pretty straightforward, but
not very robust.  what i'm wondering is if there might be a way to specify
the most recent available bionic version of openssh-server, satisfying
dependencies from bionic as needed but preferring focal for most of
everything.  any apt-get experts here?
