Ok, this was something, I scared, but also something I previously warn. There was some post remove errors in versions 0.5.0-7 to 0.5.0-10, and only way to get rid of them was to re-flash the device. This was fixed in 0.5.0-10. You may also try force update in X terminal, but you probably need to re-flash

The reason for these errors was in post-remove script which tryed to delete all config file addresses for pyKake from lircd.conf. There was something in it, which caused the error. I think I now know the problem which was line trying to reload lirc in it and if lirc is removed in part of remove(and it will, if pyKake is the only app which use it), that would cause the problems. Next version will (again) include post-remove script to test that scenario and because of that may cause the remove error, but that we will see, later today (so, when it is online, do not update to 0.5.0-12, it might cause some problems, I will post a note here, if it safe to install and remove).
