Hi,
I just did a fresh install of OpenHab2.0 and it fails to start.
When I check the JDK version it says -
" root@raspberrypi:~# java -version
java version "1.6.0_38"
OpenJDK Runtime Environment (IcedTea6 1.13.10) (6b38-1.13.10-1~deb7u1+rpi1)
OpenJDK Zero VM (build 23.25-b01, mixed mode)
"
I followed the instruction in -
I tried to uninstall the jre but got the following error -
root@raspberrypi:~# dpkg --get-selections | grep jre
