upgrade breaks sparky-aptus-upgrade sudo password is denied / invalid

[galen]

after recent upgrade
sudo apt-get update
sudo apt-get upgrade
do work
but
sparky-aptus-upgrade denies login,
it reports invalid password
The LXDE panel icon runs
remsu /usr/bin/sparky-aptus-upgrade
and it reports invalid password when correct password is entered
:(

Do you have separated root password?
If yes, remsu uses the root password (su) instead of sudo.
Did you reboot after upgrade and try run the upgrade tool again?
Upgading systemd needs rebooting the service sometimes to work fine.

my fault as I face palm,
I have a root password setup which I had forgotten that I did setup
