guys, looks like your devs screwed a bit the debian package:
I installed the debian package (buster) and after the installation
the apt file insync.list points to ubuntu xenial
please fix this ASAP, not a good idea to mix ubuntu packages with -stable- debian installations.
clip from postinst of the deb installer…
elif ! [ "$distributor_id" = "Debian" -o "$distributor_id" = "Ubuntu" ]; then distributor_id="ubuntu" distributor_codename="xenial"
