I follow the instruction : Ubuntu 12.04 (Precise)

sudo sh -c 'echo "deb precise main" > /etc/apt/sources.list.d/ros-latest.list'

Set up your keys

   wget -O - | sudo apt-key add -

sudo apt-get update

then ,that is this :

Hit precise Release Get:1 precise/main i386 Packages [1,641 kB] Ign precise/main TranslationIndex
Hit precise/main Translation-en Ign precise/main Translation-en_US Fetched 1 B in 3s (0 B/s) W: Failed to fetch gzip:/var/lib/apt/lists/partial/packages.ros.org_ros_ubuntu_dists_precise_main_binary-i386_Packages Hash Sum mismatch

E: Some index files failed to download. They have been ignored, or old ones used instead.

then ,I type:

sudo apt-get install ros-groovy-desktop-fullat
that is this:
Reading package lists... Done
Building dependency tree       
Reading state information... Done
E: Unable to locate package ros-groovy-desktop-full

I then check the directory:

bob@bob-robot:/etc/apt/sources.list.d$ ls ros-latest.list

Try to remove the lists directory under /var/lib and then creat it again:

cd /var/lib/apt
sudo rm -fr lists
sudo mkdir lists
sudo mkdir lists/partial

And try updating again

sudo apt-get update

After that, follow the instructions under the installation guide again (Configuring repositories, set up the keys updating apt-get and installing)

Any other solution? I've been waiting for a week, but nothing got better on the source.
