In software update says 4.2-3

But have updated and reboted
have new UI plasma is updated
and kopano core not working to start with
systemctl start kopano-server.service
and for see if was active take status for start nothing helped

I’m not sure I understand what you want to express. Did you try to upgrade and in UCS it still says it’s 4.2?

Good Morning,
before upgrade says that 4.2-3 and runing upgrade take about more an 6 hour, started apache then could coming in to admin site checked software update there was install 4.3 and runing that and that fixed something.
I reboot computer and after that working everything Kopano core too working good.
Hope you understand little of my english.
