Comment 0 for bug 1528886

Tested on krillin with SIM and data enabled
OTA 8.5 stable channel
Also Arale on proposed 201

Ensure phone has latest updates installed
Check for update on Wifi and it reports software is up to date
Turn off wifi and go to updates panel again
Checking for updates ... is shown and I see one of 3 results

In all cases the log reports:

2015-12-23 15:34:19,394 - WARNING - void UpdatePlugin::Network::checkForNewVersions(QHash<QString, UpdatePlugin::Update*>&)

2015-12-23 15:44:56,007 - WARNING - Reply is not valid.

In some instances I see this but not all, this is logged when the phone locks and resumes
2015-12-23 15:36:18,625 - WARNING - QObject::killTimer: Timers cannot be stopped from another thread
2015-12-23 15:36:18,625 - WARNING - QObject::startTimer: Timers cannot be started from another thread

One time I saw
Connect to the Internet ...

In anther case it displayed this after around 5 mins when I did not allow the phone to turn off:
Software is up to date

In all other cases Checking for updates never finished
