that would require a change to the systemd unit file, telling weewxd to use
weewx.conf-5.0.0b16-5.4.0 instead of weewx.conf. i am pretty sure that your
system is still using weewx.conf. if not, please provide more information.

if you choose to use the maintainer's version, or if you mess with the
'version' field, then the apt logic will copy the maintainer's version into
weewx.conf.

if you modify weewx.conf, then there should be no confusion. weewx.conf is
what your system uses unless you change the systemd configuration.

it is quite possible that the b16 is messing things up, resulting in you
getting a maintainer's version (which could look just like your original conf,
but with mangled/reformatted comments).
we have had issues with the operating systems' comparisons of versions. i
don't remember if this is true for dpkg, but there were cases where 5.1.0b10
was treated as newer than 5.1.0, for example.
apologies for the previous, lengthy response that did not address your
questions directly.
