Using Rpi 3B+ with openhab (hassle free) 2.5M1 build 1575.
I have no idea what have happened, but after installing the latest ipcamera binding, I had to clear the cache and tmp. When openhab restarts, this happen:
2019-06-12 01:02:30.919 [ERROR] [core.karaf.internal.FeatureInstaller] - Failed installing 'openhab-binding-hue, openhab-binding-modbus, openhab-voice-googletts, openhab-misc-openhabcloud, openhab-binding-smaenergymeter, openhab-binding-tplinksmarthome, openhab-transformation-javascript, openhab-binding-network, openhab-persistence-influxdb, openhab-ui-habpanel, openhab-action-pushover, openhab-binding-zwave, openhab-binding-mihome, openhab-binding-chromecast, openhab-ui-restdocs, openhab-binding-netatmo, openhab-ui-basic, openhab-transformation-map, openhab-binding-openweathermap, openhab-ui-habmin, openhab-binding-expire1, openhab-ui-paper, openhab-transformation-scale': Unable to resolve root: missing requirement [root] osgi.identity; osgi.identity=openhab-binding-network; type=karaf.feature; version="[2.5.0.SNAPSHOT,2.5.0.SNAPSHOT]"; filter:="(&(osgi.identity=openhab-binding-network)(type=karaf.feature)(version>=2.5.0.SNAPSHOT)(version<=2.5.0.SNAPSHOT))" [caused by: Unable to resolve openhab-binding-network/2.5.0.SNAPSHOT: missing requirement [openhab-binding-network/2.5.0.SNAPSHOT] osgi.identity; osgi.identity=org.openhab.binding.network; type=osgi.bundle; version="[2.5.0.201906102020,2.5.0.201906102020]"; resolution:=mandatory [caused by: Unable to resolve org.openhab.binding.network/2.5.0.201906102020: missing requirement [org.openhab.binding.network/2.5.0.201906102020] osgi.wiring.package; filter:="(osgi.wiring.package=fr.bmartel.speedtest)"]]
I have no addons defined in the addons.cfg file.
I removed the latest ipcamera binding again, cleared the cache and tmp once again, and rebooted. But still the same.
It seems like it´s most of the binding from PaperUI. The manual installed bindings seems to work fine. Without beeing able to enter PaperUI, I can tell for sure, that the old ipcamera binding and IHC binding are running. (those are manually added to addons folder). But zigbee, z-wave, Unifi, Velux are not running…
I have cleared cache and tmp many times, also with the M1 build 1575. But this has never happened before. And I have no idea how to solve this. So I really appreciate any help I can get. 
EDIT - Small change I did before installing the latest ipcamera binding. I installed ffmpeg, cause it was supposed to be used together with the latest ipcamera binding… Could that be the reason?
I´m not sure how to uninstall it… Just to make sure if it´s the cause? purge ffmpeg?
EDIT 2 - I think I managed to remove ffmpeg… But stil the same issue…
