"Checking for Updates" doesn't seem to actually run apt update [$50]

[Danielle Foré]

1. Open AppCenter and click on the Installed tab
2. AppCenter reports no updates available
3. Open Terminal and "apt update"
4. Re-open AppCenter and click on the installed tab
5. See that new updates are available.

This is partially fixed with the new daemon, but it only updates on fresh logins.

It should fulfill the case specified in this report.

I can complete this. Looking for feedback.

I would like to propose possible solutions:

1. appcenter-daemon periodically runs 'apt update'
  - there would be a lag on updates

2. appcenter runs 'apt update' on launch
  - this would make appcenter unresponsive while waiting for the updates.
  - appcenter would require user authentication to check for updates

3. appcenter optionally runs 'apt update' on launch
  - a dialog could be created "should I check for new updates"

4. appcenter provides a check for updates button

This refers to specifically the case of clicking on the "installed tab". That is more or less the "check for updates" button :)

[Richard Fairthorne (richard-fairthorne)]

Alright. I'll address that specific case by running apt updae

[Richard Fairthorne (richard-fairthorne)]

Actually addressed by calling packagekit's refresh.
