Hai, 1. I am new to linux and ROS. I am using 12.04 (32 bit) in a 64 bit machine. I tried to install ros-hydro package. After fetching (sudo apt-get install) 90-95% package, download stops by giving an error:

unable to fetch some archives maybe run apt-get update or try with fix-missing

Earlier, I installed same package in a 32 bit machine without any error.

Links that are failed to open in terminal window are accessible through web browser in UBUNTU O.S.
I am accessing internet through co-axial cable modem (does n't have any proxy settings)

Thanks, kota

It's possible that you hit the repository at a bad time.

Try running sudo apt-get update and then retrying your installation.

I've had trouble a couple times in the last week accessing all the ubuntu repositories. It's unusual but does happen sometimes.

On top of Hendrix's suggestion (meaning after you do an apt-get update) you might also want to try this:

apt-get --download-only

in order to force Ubuntu to download all of your stuff first; No install will take place. If the operation fails here, then, yes, it is a repository error. If it succeeds, move to the regular apt-get install and check if the error happens again.

Honestly, Hydro on Ubuntu 12.04 is VERY vanilla. Shouldn't fail at all.

Just in case, post you entire apt-get command, so we know what you are installing.

Try to remove completely with sudo apt-get remove ros-* And then follow : http://wiki.ros.org/hydro/Installatio... and http://wiki.ros.org/ROS/Tutorials/Ins...

Problem was occurred, when i followed procedure given in these links.. I had removed the half installed files 2 or 3 times and tried to install again. I got same problem

when you removed the half installed before reinstalling, did you find the folder in /opt/ros/hydro? If yes try to remove the folder with the command rm or rmdir

I tried with download option. I got same problem while downloading. This is the output on terminal window. (i.e. unable to open some web pages. But these links are accessible in web browser)

Hi. Just for a matter of organization, when getting back with more details, try to edit your original post, instead of "answering it". Now, for your problem, are you saying that those failed links work on a web browser ON UBUNTU itself, or is it a different machine ? This is very important.

Also, are you accessing the internet via a proxy ? Anything particular about your network ?
