I did an ‘apt-get upgrade’ of openhab2, and now it won’t even start. It looks like it has bad paths. Launching the openHAB runtime... karaf: KARAF_BASE is not valid: /usr/share/openhab2/userdata
This issue (to which you replied) really seems linux specific, so I think that the cause is different. Maybe a good reason to create a new topic instead,
What output do you get, do you have any errors in the log?
the logs under userdata/log are from june 2017. unfortunately i cant find other logs. and i dont see an output. the command-line starts for half a second and then closes.
