When I go on application manager, all my catalouges have disappeared and it says “operation failed”. When I go on update it says I have no catalogues and I can’t add new ones. When I go in download, it says the same and when I go on uninstall- it says I have no applications, when I do have applications.

When I go on the log I get this information-

hildon-application-manager 2.2.72
apt-worker: too weak to get lock from 1697.
apt-worker closed connection.
apt-worker exited.


Where I could have gone wrong-

Firstly I wanted to install "enhanced-wallpaper" which was from the devel. So I activated the devel and installed the app- everything was fine.

I then wanted to install fmobi (facebook application) for n900 (I don’t know what repository this is from as I downloaded it from the site - (http://jiikoo.com/fMobi/ )).

On the site I was told to first download and install three things so that fmobi ran smoothly of which two had to be downloaded from the xterminal method (apt-get) these were:

1. qt Mobility 1.1 (apt-get install libqtm-11)
2. Qt Quick compatibility (apt-get install qtquickcompat)
3. Qt hot fixes

So I installed rootsh, done "sudo gainroot" command and installed these files. Finally, i installed the fmobi app which works more or less fine from what I can see.
Soon after, I tried to access the application manager leaving me with the errors I mentioned at the start.

I hope I left enough information and not too much lol but can someone please help/advise me what I can do to get it working. And if there is similar threads, Sorry this is my first post to maemo.

Thank you
