Many empty/broken entries in location permission settings

[Michael Zanetti]

I was just checking my location permissions and found many empty/broken entries. I don't know what they are, or where they came from. Most of them had permission to access location enabled (I've disabled them before taking the screenshot). This feels weird and worrying from a privacy point of view.

Most likely they are apps that have previously been installed and then removed again, or some other way to generate duplicates which then break when the original goes away.

[Pat McGowan (pat-mcgowan)]

I suspect these may be apps that were side loaded and deleted. In my case the app in question is no longer installed (I see one such item on one out of 3 phones)

To view the trust store
sqlite3 ~/.local/share/UbuntuLocationService/trust.db "select * from requests"

Then you can toggle permissions and see which are the blank app names and check f they are installed or tests apps

[Pat McGowan (pat-mcgowan)]

I confirmed simply uninstalling an app shows a blank

We could fix this in settings by not showing entries for which there is no installed app, but it would seem better to fix this in the trust store, perhaps purging entries when an app is uninsatlled

[Sebastien Bacher (seb128)]

@Pat, indeed that's what mpt suggested in bug #1389775 (that bug is a duplicate btw)
