Ubuntu Software Centre does not display certain items in the Installed tab

[Paddy Landau]

As instructed, this is a split from bug 972310.

Related bugs:
Bug 973217: Show or hide technical items remains when nothing is there in Ubuntu Software Centre
Bug 973218: Ubuntu Software Centre does not display certain items in the All Software tab
Bug 973220: Ubuntu Software Centre halts when trying to display certain items in the Installed tab

Consider an item available from non-Canonical repositories, e.g. yad (ppa:webupd8team/y-ppa-manager).

If an item is already installed, there can be inconsistent results.

Using yad as an example:

1. Add yad's PPA (sudo apt-add-repository ppa:webupd8team/y-ppa-manager). Run sudo apt-get update.

2. Install yad (through the terminal or Synaptic Package Manager, as you cannot do it through Ubuntu Software Centre).

3. In Ubuntu Software Centre, go to the "Installed" tab.

4. Enter "yad". Nothing displays; it should show yad. It will display only if you select the down-arrow and choose the appropriate PPA Manager. I would expect the default action to show everything installed.

Hello Paddy. This sounds like a duplicate of bug 652914. If yad is a non-desktop app, then there should be a "Show N Technical Items" link at the bottom left of the Ubuntu Software Center window. If you see that there, please click it and the yad package should show up.

If this occurs and you can successfully view the package, please let me know and we can close this bug. If it doesn't, please let me know that as well. :)

You are right, this is a duplicate of bug 652914.
I have attached two screen-shots:
1. All Software tab, showing yad installed.
2. Installed tab (taken a few seconds later), failing to show yad installed, with no "Show N technical items".

(Second screen-shot in next comment, as I cannot attach two at the same time.)

Second screen-shot added.

Thanks Paddy! I'll set the dupe for bug 652914.
