<br>
I got stuck while installation. See below for the detail. Any thoughts<br>
would be appreciated.<br>
<br>
Phenom:<br>
 - While running "sudo apt-get install ros-diamondback-desktop-full"<br>
after downloading a few hundred MB of data, it suddenly quitted and<br>
showed "E: Unable to locate package ros-diamondback-desktop-full"<br>
 - Output of apt-get update:<br>
<a href="https://docs.google.com/document/d/1yxY6w5v6jedHXnc3omkEwCkxlT4abejfEtz3tF-D9ek/edit?hl=en_US" target="_blank">https://docs.google.com/document/d/1yxY6w5v6jedHXnc3omkEwCkxlT4abejfEtz3tF-D9ek/edit?hl=en_US</a><br>


      <- For the ROS part, the result is the same on another computer<br>
that successfully installed diamondback.<br>
 - Output of installable ROS packages on the computer. You'll see<br>
diamondback packages are missing:<br>

<br>
Tried workaround:<br>
 - The things discussed in the pages below are already tried.<br>
      <a href="http://answers.ros.org/question/702/unable-to-find-install-package" target="_blank">http://answers.ros.org/question/702/unable-to-find-install-package</a><br>

 - sudo rm /var/cache/apt/archives/*ros*<br>
 - Reboot OS.<br>
<br>
Other: As mentioned earlier, another computer which is on the same<br>
network has successfully installed diamondback. And after apt-get<br>
update on the same machine, apt-get still shows ros-diamondback as<br>
installable packages.<br>
<br>
Env: Ubuntu 10.10 Maverick<br>
<br>
Thanks in advance.<br>
<br>
Isaac<br>
