unable to locate package ros-electric-nxtall
Hi everyone! I tried to install the nxt ros package on ubuntu 11.10 and 11.04.
I followed the instructions on the ros wiki installation page, however, everytime I tried, I end up getting the "unable to locate package" message.
I know that the ubuntu natty and onieric are old versions and are unsupported anymore, so I have already changed my sources.list file with the command below before running the installation instructions:
sudo sed -i -re 's/([a-z]{2}\.)?archive.ubuntu.com|security.ubuntu.com/old-releases.ubuntu.com/g' /etc/apt/sources.list
and then I went to the Ros index page to search for the nxt and I couldn't find any package that contains "nxt" in its name. Is this the reason that the apt-get is unable to locate the package? Can anybody tell me what steps did I do wrong or is this the server side problem and how can I fix it? Thanks!
