Waiting for jockey-backend to exit

Problem: While Updating Packages,
                 i) Getting "Waiting for jockey-backend to exit" in Update Manager. &
                ii) Getting "Unable to get exclusive lock" , while updating using apt-get update
                iii) Updating Cache problem

What is jockey-backend ?

Jockey is a tool for installing third-party hardware drivers.

Jockey provides the infrastructure and the user interface for finding and installing third-party drivers which are applicable to the computer. This includes drivers which are added or updated after the release of a distribution, or drivers which cannot be included into the distribution for various reasons (CD space limitation, licensing problems, etc.).

Solution :
You only need jockey for enabling restricted drivers, afterwards you can safely disable it.

Open Terminal and type following commands:

1) To get into root mode
    sudo -i

2) To check the process id of jockey
    ps -e | grep jockey

Output: 2982 pts/0 00:00:00 jockey

remember the process id(2982)

3)Type the following to stop/kill the process

  sudo kill -9 [process_id]

 sudo kill -9 2982

No Synaptic Package Manager in Ubuntu 11.10

 ‘Synaptic Package Manager’ tool has been dropped from the latest builds of Ubuntu 11.10 Oneiric Ocelot.

The removal of Synaptic Package Manager have been planned since the inception of the Ubuntu Software Centre. Many of the advanced features Synaptic currently provides are ear-marked for inclusion in the Ubuntu Software Centre.

Well, I really don't like SOFTWARE CENTER as it takes forever to start up and it doesn't list all packages. I mostly use Synaptic and apt-get for installing packages.

So I have installed Synaptic package from the repository.

sudo apt-get install synaptic
