Also affects 12.10 Amd64 release.

It's because the apt cache is not up-to-date. if you run "sudo apt-get update", close and re-open LSC, it should show all the applications.
Still, LSC should detects this and update the cache itself

I have run "sudo apt-get update", which I believe had already been tried. LSC cannot find applications that have been installed via synaptics... E.g. on my installing bluefish editor, Lubuntu Menu correctly added a new menu entry called "Programming". LSC cannot see this group, nor can it see the fact I have firefox installed when I check out the list of installed applications under 'Internet'.
I have installed lubuntu-12.04-alternate-amd64.iso via KVM and it shows the same problem upon installation. I will ask 12.04 to fully update and report back the result.

The same behavior is seen in my updated 12.04 (64Bit) Installation on KVM.

I think I am hitting this bug in the current (20121215) daily lubuntu-desktop image. I tried updating the cache as suggested, but that did not seem to resolve the problem.

I'm unable to see even currently installed software under LSC.

I added a tag for raring

Did apt-get update still no packages are displayed after clicking the package category. After clicking the installed software no packages are displayed.

Also affecting me on Lubuntu Raring beta. Was working in 12.10.

I can also confirm this bug of LSC not showing any software in Raring beta 3.
I get the following error trying to reinstall LSC:

Traceback (most recent call last):
  File "/usr/sbin/lubuntu-software-center-build-db", line 103, in <module>
    single_pkg = DE.DesktopEntry(base_folder+item)
  File "/usr/lib/python2.7/dist-packages/xdg/", line 33, in __init__
  File "/usr/lib/python2.7/dist-packages/xdg/", line 42, in parse
    IniFile.parse(self, file, ["Desktop Entry", "KDE Desktop Entry"])
  File "/usr/lib/python2.7/dist-packages/xdg/", line 81, in parse
    raise ParsingError("Invalid line: " + line, filename)

The problem is the /var/cache/lsc_packages.db stays empty after install.
It does work in 12.10, hope this gets fixed before the release.

My hunt for a reasonably competent python programmer to maintain LSC have been in vain. Until someone succeeds LSC is not getting updates / bug fixes. Sorry about this, I do keep trying!

Downgrading python-xdg to Quantal fixes the database building.
Then I had problems with LSC itself; only showing installed packages, so also downgraded that to Quantal.
Now it works fine.

Replace /usr/share/pyshared/LSC/ with the attached file. When LSC is started it will ask for the admin password and then build the database to include all the installed applications.

The attachment "" seems to be a patch. If it isn't, please remove the "patch" flag from the attachment, remove the "patch" tag, and if you are a member of the ~ubuntu-reviewers, unsubscribe the team.

lubuntu-software-center (0.0.5~bzr161-0ubuntu1) saucy; urgency=low

  * New upstream snapshot.
   - Rebuild database when LSC start if there is no database (LP: #1078820).
