When i uninstalled a deb package i get this:

    Processing triggers for bamfdaemon ...
    Rebuilding /usr/share/applications/bamf.index...
    Processing triggers for desktop-file-utils ...
    Processing triggers for gnome-menus ...

Do i need to do anything?

These are "business as usual" informational messages about package interactions (for example "triggers for gnome-menus" may be "remove this program's launchers from gnome-menus"). No action is required on your part. This may be of interest: raphaelhertzog.com/2011/05/30/… –  Piskvor Aug 21 '12 at 19:53
    
Thank you all for the responses. They were all very helpful. I have a better understanding of the these pre/post triggers. Thanks again. –  M_M Aug 22 '12 at 21:55
    
@user84750 It would be useful if you accept one of the answers (decide which one answered your question best) so that the question is no longer listed as unanswered on the system. –  Steve Kroon Aug 23 '12 at 7:10

Those are normal messages to get when dealing with packages, and are actually there to prevent you from having to take any actions. Without those triggers, you would have to logout/login or reboot for some changes to show up.

The reason they are there are to give other tools a chance to update - for instance, the list of applications in the unity dash would need to update to not show newly removed items. There are other triggers for man pages (documentation), grub bootloader (new kernel versions), and many others.

You don't need to do anything - these are informational messages so that you can monitor the progress of the (un)installation.

No, you don't have to do anything because it is normal. That line is the output of the terminal where it shows all the procedures that is doing.

You will know when an error happens, trust me, you will. In error cases scenario you will get an output with several error words or the E: character before a line.

To give you an idea and compare, I leave this output that I had.
