Indicator-updatemanager is small update indicator in system-tray that informs about available updates. It will disable the annoying popup ‘Update Manger’ window.

It’s in an early development stage and might still have bugs. But it works.

This is developed by Jonas Frei, and the code is hosted on launchpad.net/indicator-updatemanager. You can download and build from the source

I never really was satisfied with the update management and that the update-manager just pops up without any indication. So i made this little application which integrates in the application menu and notifies the user about updates.
To build the vala sources, you will need the following dependencies:

- aptitude
- libgtk2.0-dev
- libgconf2-dev
- libappindicator-dev
- libnotify-dev
- libglib2.0-dev
- libvala-0.12-dev
- valac

Just run the usual:

./configure
make
make install

The Webupd8 PPA has built this for Ubuntu Precise 12.04 and Oneiric 11.10. So as an alternaive, Ubuntu 12.04 and 11.10 can add the PPA and install it by executing following commands in terminal:

sudo add-apt-repository ppa:nilarimogard/webupd8
sudo apt-get update
sudo apt-get install indicator-updatemanager
