The version numbering of kopano community and supported version are different.
Which give problem when you want to upgrade from communtie to supported.
apt-cache policy kopano-server
*** 126.96.36.1998-0+53.1 100
500 https://download.kopano.io/supported/core:/final/Debian_9.0 Packages
no, this look “almost” ok but it it not.
188.8.131.528-0+53.1 100 around 15 Feb 2018
184.108.40.206-0+27.1 500 just release.
Is this intended? because the community version is updated daily?
This make imo, things more confusing.
Just a thing i noticed.
