Bug Description

Hello, I have a problem on my M10 FHD witch is on rc-proposed channel (r173 now). I can't receive any updates for system image or any installed app. I even receive a notify in message indicator, but when I open update manager it searches for updates and found nothing (saying that my system is up to date). There should be updates at least for some apps and 2 system image updates since then. Rebooting and shutdowning device didn't help. My Meizu MX4 is updating normally with
the same network connection.

It would be very nice to have some workaround and fix this.

`system-image-cli -n -vv` ouput:

Thank you for reporting this, I'm not sure whether or not that traceback is benign. We'll have to hear from Barry/a S-I maintainer to know for sure.

Problem is found and fixed. It was in ~./local/share/ubuntu-system-settings folder. Somehow normal structure of this folder messed up.

Normally, there must be 1 file "updatestore.db" but when it broke there were no such file, only an empty folder "Pictures". (???)

How can it be possible? Manual intervention is excluded. I didn't even open hidden folders for weeks, I didn't make my system folder RW, etc.

For some reason permissions were wrong. I can't reproduce permissions state when the problem came up because I renamed this folder from root. Now I changed permissions of old folder to correct ones and everything is working.

But it is still a bug, because I didn't open Terminal, didn't connect to device from PC or even open a File Browser for >2 weeks. Just using phablet as a regular user. Permissions changed by something else and it is interesting...what could cause that?
