USC adds icon to launcher for apps that didn't install

[Alan Pope 🍺🐧🐱 🦄]

I just did this:-

Open Applications Lens
Search for app which I may or may not have installed (liferea)
Click the link to install it
Ubuntu software center opens, I click "install".
Due to a configuration issue on my network* (see below) USC complains that the package is untrusted. Dialog says "Ok" or "repair", I just choose "Ok" (like many users would).
Icon for liferea appears in launcher
icon doesn't work.

Further investigation reveals that USC didn't actually install liferea at all due to the network issue, but still installed it.

Now I appreciate that I have a broken network, but it seems incorrect that USC should add the icon to the launcher and leave it there even though the app didn't install and can't install. So I end up with a broken icon, thinking the install worked but the app is broken.

Explanation of issue which caused this.
I use squid-deb-proxy and squid-deb-proxy-client at home to cache downloads.
Whilst away from home I switched my sources.list to a different mirror which isn't listed in my squid-deb-proxy config
When I got home I didnt switch my sources.list back and as the new mirror isn't listed I get 403 errors whenever updating or installing apps. So USC got a 403 when doing the "apt-get install liferea" (or whatever it did under the covers)

I've asked Alan to provide an image of the dialog that is the concern for me, the icon removal should be fixed when unity enable the icon removal script, but unity have taken over the removal of icons see bug 966197

[Varun Priolkar (varunpr97)]

Its a regression in the unity 5.10 which introduced the animation.

This is a unity issue, I added a branch for this and removed the USC task.

Is this planed for a SRU to precise? Given that its a relatively simple fix it would be nice to get it to the 12.04 users too.

@mvo, this commit is already in unity 5.12 which have been in Ubuntu for a while :-) updated the status.
