Cannot reinstall a previously uninstalled application

[Jean-Baptiste Lallement]

current build number: 221
device name: krillin
channel: ubuntu-touch/rc-proposed/bq-aquaris.en

Test Case:
1. Go to the app store, and install an app (I install sudoku from Sylvain Becker)
2. Upon installation, go to the app scope, and verify that the app is installed
3. Long press the app icon to go to the app details, and tap on 'uninstall'
4. Verify that the app no longer appear in the app scope
5. Go to the app store again, select the same app and try to re-install it.

Expected Result
The button 'Install' is displayed and the app can be installed

Actual Result
The button is labelled '0%' and is not clickable. The app cannot be resintalled.
The state is cleared after a reboot and the app can be installed.

I have confirm that this happens on rc-proposed but doesn't on my stable dogfood device so is definitely a regression.

guessing its related to u-d-m changes?

[dobey (dobey)]

This is because when we when we check u-d-m to see if there's an existing download, it seems to claim there is, at 0%.

Does rebooting solve the issue?

[Pat McGowan (pat-mcgowan)]

Per the description reboot clears it and app can be installed
