Ok, it finally happened again :) My setup: Krillin, rc-proposed (after OTA9 freeze), r232 The content of /var/log/ubuntu-location-service/com.ubuntu.location.INFO is I0116 21:01:57.030153 3319

/var/log/ubuntu-location-service/com.ubuntu.location.ubuntu-phablet.invalid-user.log.INFO.20160116-205932.3293 I don't have any other file in that folder (I cleared it about a week ago, and I'm quite sure location worked OK after I cleared those logs, so I don't think they had anything useful to offer) The file /var/log/upstart/ubuntu-location-service.log has the following content: name ->
