Comment 5 for bug 1607034

Bug reproduced.

Here's what I did
0) made sure mobile data was connected
1) connected to WiFi
2) downloaded update using WiFi
3) popped Updates page
4) disabled WiFi from the Network indicator and waited for the device to switch to mobile data
5) went back into Updates page
6) at this point it seemed stuck on "Looking for updates...", so I popped the page again
7) went back into Updates once more
8) This time I could see the update with the install button
9) tap on install
10) System-settings "In progress" fullscreen dialog shows
12) After 10 minutes, nothing yet, still "In progress"
13) connect to Wifi using Network indicator, nothing happens, still "in progress"

Please find client.log attached

NOTE: nothing is written to client.log when I tap on install and I get the "In progress" fullscreen view
