Fresh install won't work with 0.0.3.Alpha2 (Migration Exception)

Afterwards I tried a 0.0.3.Alpha1 fresh install which works without any problems.

Anyway, here’s the error log:

Thank you for your effort! I’ve manually added the gateway, sensors and stuff again, so I didn’t need to apply the backup. Now everything is working (and wow, the interface, just everything is way more polished and functional than I thought it would be in an alpha release, so great work 👍 - just didn’t want to always only mention the negative things 😉 ).

I’m not closing this issue for now as I want to do some more debugging in the next few days - the information given in your last post will be helpful I think!

MyController is using H2DB database, will be stored at mycontroller/conf/mycontroller.h2db. Extract MyController Alpha2 version and run it. If you face this issue again, stop and remove mycontroller/conf/mycontroller.h2db and start it again.

Ok, so MyController will recreate the file then? Great, I think that might help me with debugging.

If you still face the issue try to upgrade your Raspberry PI kernel.

That’s something I will certainly try. Also I noticed I hadn’t installed a lot of updates since the Raspberry Pi (BTW, it’s a modell B rev 2.0) lied around for a while… Maybe that already helps.

But first I will need to find an empty SD-card so I don’t break my working system while experimenting…

Well, I have no idea what went wrong.

Now after my new SD-card arrived, I installed a fresh Raspbian, configured the locales etc., installed Oracle Java and followed the exact same steps in the installation instructions again. Everything works fine now… Sorry and thank you for your effort! So yes, this issue can be closed.
