Error: Install Hydro in Ubuntu 12.04.5
Dear All,
I have followed the ROS website instructions for installing Hydro to Ubuntu 12.04 running in Macbook pro. However, I encountered errors as follows:
W: Failed to fetch http://extras.ubuntu.com/ubuntu/dists/precise/main/source/Sources Hash Sum mismatch
W: Failed to fetch http://extras.ubuntu.com/ubuntu/dists/precise/main/binary-i386/Packages Hash Sum mismatch
W: Failed to fetch http://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.
Reading package lists... Done Building dependency tree Reading state information... Done E: Unable to locate package ros-hydro-desktop-full
May I know how to solve this issue?
Thank you very much.
Regards, Jayden

Looks like from the error message you are looking at installation instruction for Ubuntu, not the one for Mac OSX.
UPDATE: That seems Ubuntu problem that doesn't necessarilly pertain to ROS. Referring to e.g. this QA and looking specifically at your errors, you may want to do:
rm /var/lib/apt/lists/extras.ubuntu.com_ubuntu_dists_precise_main_source_Sources
rm /var/lib/apt/lists/extras.ubuntu.com_ubuntu_dists_precise_main_binary-i386_Packages
rm /var/lib/apt/lists/packages.ros.org_ros_ubuntu_dists_precise_main_binary-i386_Packages
apt-get update
And try installation again.
