GPS and location detection not working on Nexus 4

[Tomas Öqvist]

Mako with MultiROM, utopic r235

None of the apps I have tried including Weather, Google maps, OSM Touch and SensorStatus are able to use the phones GPS. The SensorStatus app actually reports "Found supported backend", but finds no position or other GPS data.

Location detection on the other hand is doing something, but it is really far off when it comes to determining the actual location of the device. The Weather app suggests my location as Vänsjö, Jämtland, which is about 400 km north of Stockholm where I am at. OSM Touch reports "no location available" and Google maps "Your location could not be determined"

I don't know if the GPS has to "waken up" somehow, but it has not shown any form of life for me on Ubuntu Touch, even though it works perfectly fine when booting the phone as Android.

I noticed this a few weeks ago and it has not been rectified.

I have asked the osmtouch developers if they know abouut it

Did Iyou ever have location in OSM Touch? I don't think I have, certainly not with GPS. Neither in OSM Touch nor any other app.

[jeffcooper (jeff-cooper)]

Yes, I did have location detection working well in OSM Touch. I don't know if it was GPS or not but it certainly was working.

[Tomas Öqvist (tomoqv)]

It was probably not the GPS, because I have also gotten location in OSMTouch at some point, but it was so far off that could not possibly be a GPS position. I have copied this bug report to https://bugs.launchpad.net/ubuntu/+source/indicator-location/+bug/1368367 because I think that bugs against Touch Preview Images are no longer monitored by the Ubuntu Team. Please continue the discussion there.

Digging into it today I found the following after running OSM Touch and touching the location detection arrow :-

phablet@ubuntu-phablet:/$ cat /var/log/ubuntu-location-service/com.ubuntu.location.WARNING

E0912 08:52:39.514560 2419 skeleton.cpp:177] Error creating session: Client lacks permissions to access the service with the given criteria

So it seems like a permissions issue?

Also, going back to the start of the warnings:-

phablet@ubuntu-phablet:/$ cat /var/log/ubuntu-location-service/com.ubuntu.location.ubuntu-phablet.invalid-user.log.WARNING.20140809-134227.916

All warnings are the same as above until:-

phablet@ubuntu-phablet:/$ cat /var/log/ubuntu-location-service/com.ubuntu.location.ubuntu-phablet.invalid-user.log.WARNING.20140822-100144.924

E0822 10:01:44.903519 1942 skeleton.cpp:177] Error creating session: Client lacks permissions to access the service with the given criteria

Then:-

phablet@ubuntu-phablet:/$ cat /var/log/ubuntu-location-service/com.ubuntu.location.ubuntu-phablet.invalid-user.log.WARNING.20140827-070346.912

Then the rest are the permissions errors with one more of the "Error wile setting up access" errors.

And for reference:-
phablet@ubuntu-phablet:/$ system-image-cli -i

@jeffcooper: Could you please also update https://bugs.launchpad.net/ubuntu/+source/indicator-location/+bug/1368367 with this information?

[jeffcooper (jeff-cooper)]

Also, thinking back, location detection was definitely working on 1st of July which was prior to me upgrading to utopic.

[jeffcooper (jeff-cooper)]

Missed the post containing the link

https://bugs.launchpad.net/ubuntu/+source/indicator-location/+bug/1368367

while posting further today.

It's dificult to know where is the most appropriate place to post bugs but I don't think that this bug is to do with the location indicator. It is more lkely to be do do with the location service. How about

https://bugs.launchpad.net/ubuntu/+source/location-service ?

[Tomas Öqvist (tomoqv)]

You are probably right, I missed that one. I will report the bug there as well.
