Just testing with Ubuntu 20.04 Lts.
Did a fresh installation of stable openhab2 2.5
Webserver on Port 8080 is running, but only get not found message of jetty
In log openhab i can see found multiple interfaces and all IPv4 interfaces are ignored, so no dashboards coming up
Allready tried to bind to a special ip with /etc/default/openhab.conf, but errors are still the same
