Error: Unable to locate package neutron-server E: Unable to locate package python-neutronclient

here is the grizzly guide:
http://docs.openstack.org/grizzly/openstack-network/admin/content/install_ubuntu.html

Thank You for the reply.
I followed the approach present in the above mentioned Grizzly guide and now facing a different issue while running the "python-quantumclient" install command. I get an error saying "the requested package has been moved out or not yet created"
I have uploaded this "deb http://ubuntu-cloud.archive.canonical.com/ubuntu precise-updates/grizzly main"
in sources.list file.

Appreciate the help in letting me know what am i doing wrong.

First:
I get the following 404 error when i run the apt-get upgrade command.

apt-get upgrade should run after apt-get update

in my notebook (which doesn't install quantum from ppa before), i add the grizzly ppa and update and run
# apt-get install quantum-server python-quantumclient
everything is fine, no error is printed

it seems it is caused by wrong state (or wrong config) of apt, not caused by quantum, so i think you'd better search and fix it by yourself
========================================================================

after google the error you reported, i find this:
http://ubuntuforums.org/showthread.php?t=1905494
http://askubuntu.com/questions/311842/how-do-i-fix-apt-errors-w-failed-to-fetch-hash-sum-mismatch
which recommends affected people to rm (you can backup this dir instead of rm it directly) /var/lib/apt/lists/partial/* (not the partial dir itself), and run apt-get update

ps: in my apt sources.list, precise-security part (this is not set manually , not related the quantum ppa) is :
deb http://mirrors.163.com/ubuntu/ precise-security main restricted
deb-src http://mirrors.163.com/ubuntu/ precise-security restricted main multiverse universe #Added by software-properties
deb http://mirrors.163.com/ubuntu/ precise-security universe
deb http://mirrors.163.com/ubuntu/ precise-security multiverse

since i'm in china, the host domain name may different from yours, but the rest part should be same, please check your config file

Yes Some issue with OS i happ to reinstall and its working fine.
Thanks Again

Thanks ZhiQiang Fan, that solved my question.
