You could go back to the previous configuration, but read on...

Perhaps "posttls-finger" is left over from an earlier install? Did
you build and install Postfix from source?
The OpenSSL version looks typical enough, is that "/usr/bin/openssl"
or some other version? What does "ldd" show for this binary?

Here we see that the same "unknown state" issue happens with Postfix
out of the picture. Both for local connections and connections to
Gmail. So this should be pursued on a suitable Ubuntu forum.

I very much doubt that Ubuntu shipped this Postfix version. Looks
like you've built your own, and installed it on top of Ubuntu's
package. That requires some care and skill. You're typically
better off sticking with the bundled package or a "backport".

Not surprising, that's left over from the Ubuntu package.
