Looking deeper into my command install, it looks like you're doing a
reinstall somehow.  The "Selecting previously unselected package mythweb."
line gave me that hint.  Here's my output log on the new mythweb install:

Reading package lists... Done

Reading state information... Done
The following NEW packages will be installed:
  mythweb
0 upgraded, 1 newly installed, 0 to remove and 0 not upgraded.

Configuration file '/etc/default/mythweb'
 ==> File on system created by you or by a script.
 ==> File also in package provided by package maintainer.
   What would you like to do about it ?  Your options are:
    Y or I  : install the package maintainer's version
    N or O  : keep your currently-installed version
      D     : show the differences between the versions
      Z     : start a shell to examine the situation
 The default action is to keep your current version.
*** mythweb (Y/I/N/O/D/Z) [default=N] ?

I'm not quite sure what to make of this other than to believe that there's
a difference in the 18.04 and 19.10 packaging system and there's probably a
packaging bug to be fixed in 18.04 that does not exist in 19.10.
