In the Software Centre, under Installed Software, I have a number of packages marked as coming form "other". Where might these have come from? The libdvdcss2 entry does not surprise me, but I have no idea where the qt and update-manager entries have come from.

As far as I'm aware I have never installed these packages from a PPA, or installed them manually.

Update: After taking the screenshot I removed the qt packages because I don't actually need them. However the output of $ apt-cache policy update-manager is:

  Installed: 1:0.142.21
  Candidate: 1:0.142.21
  Version table:
 *** 1:0.142.21 0
        100 /var/lib/dpkg/status
     1:0.142.20 0
        500 maverick-updates/main i386 Packages
     1:0.142.19 0
        500 maverick/main i386 Packages

I'm wondering if it could be to do with the maverick-proposed repository.

Interesting question, and yeah, I see that too... :) – JanC Nov 7 '10 at 9:52
@Janc Do you have the proposed repositories enabled? – 8128 Nov 7 '10 at 9:59
Yes, but somehow things like libqt4-dbus and update-manager aren't in -proposed. Maybe they got removed because of a problem? – JanC Nov 7 '10 at 10:11
I think you're right :) – 8128 Nov 7 '10 at 16:57

The version which is currently installed is no longer available on any of the configured repositories. Do you have the -proposed repository enabled ? I believe there were some recent uploads to update-manager there which were rolled back, that would explain it...

About to the main part of the question, Software Center is only able to determine the "Origin" of a package if it is still available from an active repository, when the Origin is unknown it's shown on the "Other" item.

From the terminal run:

apt-cache policy libqt4-dbus

If the repository from which you got the packages is still enabled you will see it on the list.
