- Textual description of the issue:
I'm trying to get to work with the Kura (iot.eclipse.org/java/tutorial) example, but I have some errors and it doesn't work for me properly. As stated above, I am using Raspberry PI 2 B+ with Java 1.8.0_65 preinstalled.
Basically, when installing Kura using the `sudo dpkg -I kura_1.4.0_raspberry-pi-2_installer.deb` or ('kura_1.3.0' for example), the dpkg complains about missing some dependencies and fails, hence, I used the `sudo apt-get install -f` to download them automatically. The thing is when the later command runs, it breaks the `isc-dhcp-server` and makes it fail on the reboot of the Raspberry Pi "plus the RPI's IP address got changed to a static one instead".
Furthermore, when accessing Kura's website to install the IoT greenhouse package, I encounter weird internal error that I am not able to fix (logs are attached at the end of the description!). Here is how the phenomenon happens:
First, navigating to the `MqttDataTransport` in the Services section "on the left hand side of the screen" and changing the broker-url to `mqtt://iot.eclipse.org:1883/` and setting the `connect.auto-on-startup `to true from the DataService section, Kura encounters internal server error on Connect and doesn't let me to proceed "i.e., remains disconnected".
Moreover, when trying to install the `http://iot.eclipse.org/java/demo/org.eclipse.greenhouse.iot-0.1.0.dp` package in the "install/upgrade" part in the "Packages section", it says that the file was successfully downloaded, but nothing is shown in there; the area says "no packages installed" and even no file(s) is/are found in the RPI folders. In turn, the Greenhouse Publisher didn't show up as expected in the "Service section".
I don't know whether the tutorial is working! I checked the connections too many times. So i think the problem is in another place.
Could you help me in some way?
Thank you so much for your time.

Kura logs: Attached!
[1] [kura.log]
[2] [kura-console.log]
On a side note: Also I followed other tutorials on how to install Kura on RPI
[1] www.opensourcerers.org/installing-and-running-eclipse-kura-on-a-raspberry-pi-b-model-1/
[2] eclipse.github.io/kura/intro/raspberry-pi-quick-start.html
According to them, they ask to purge dhcpcd5 and remove network manager first then install Kura; whereas according to the main tutorial, it installs Kura without removing/purging dhcpcd5/network manager settings. I tired both, but still the issue persists.
Thank you so much, and please let me know if additional pieces of information are needed. Looking forward to your reply. Mohab
