If you installed rubygems it would seem impossible for the command
update_rubygems not to be found. Perhaps it is not installed.
Perhaps someone is familiar with Ubuntu's ruby packages and can guide
you with what it is that isn't working right. Generally, the
distribution packages lag too far behind and seem to be an obstruction
which is one of the reasons why things like rvm have become popular.
I strongly suggest that for rails on Ubuntu you use the method from
http://ryanbigg.com/2010/12/ubuntu-ruby-rvm-rails-and-you/
as an earlier poster already suggested. You are in for a great deal
of pain trying to do it using the ubuntu repositories.

I suppose the way to install it would be...
sudo apt-get install rubygems
On my ubuntu 10.04 LTS (but not using any Ubuntu ruby packages
whatsoever because I use the enterprise ruby packages)
If rubygems package is installed, you should be able to easily run 'sudo
update rubygems'

i think i already install rubygem below is my command to verify that
rubygem is install in my system.i also try to use apt-get install
rubygem but the system show that my rubygem is already new version.below
all the output:-
root@oneadmin:~# apt-get install rubygems
Reading package lists... Done
Building dependency tree
Reading state information... Done
rubygems is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 4 not upgraded.
which installs all gems in my user directory - no sudo needed. BUT
bundler does not obey this setting and ask for sudo password and
installs them into the system.
I think the easiest way to get rubygems and bundle working "locally"
is setting something like
and there is no problem to install sinatra and thin. from that thread
I conclude you do not have the right version of rubygems installed try
to install the version from 11.10
I can only suggest once that again that you start from the beginning
using rvm (if you have installed rubygems from the repository then
uninstall it and manually install an appropriate version) and when you
come to a problem come back and ask about that particular problem.
When I suggested previously that you did this you just said "i already
try this suggestion before but still not working and i cannot install
sinatra and thin using this method." which is not very specific.
This may not fix the problem but once you are using rvm you will be
better aligned with most people here (I believe) and will therefore be
more likely to find a solution.
