Installing apps blocks description pages from loading

[Cassidy James Blaede]

To reproduce:
1. Open AppCenter
2. Find an app
3. Click on the app (to go to the description page)
4. Install the app
5. Find another app
6. Go to its description page while the other app is still installing

Expected result:
The description page for the new app loads and you can click install to queue the installation to happen after the other app is finished.

Actual result:
A GTK Spinner until the current app is installed, then the page loads.

Since apt does not support parallel transaction I have to wait for appstream integration in libappstore in order to fix this bug. So retargeting it for 0.2 milestone.

Mario, can you provide a link to a relevant discussion/bug for libappstore so we can keep up with this? I feel this is a blocker to shipping AppCenter with elementary.

We might have to backport aptcc and packagekit to get this feature. There was a significant rework in one of them and possibly an API break to implement this. I'm not sure this is a reasonable thing to do.

[Mario Guerriero (mefrio-g)]

Sergey PackageKit supports parallel transactions but until apt-get won't be made thread safe we won't be able to fix this bug.

Cassidy report the bug in libappstore's launchpad page if you want.
