cant install rails in ubuntu 9.10 in my eee pc

Question

i am trying to install rails in my eee pc with the last version of ubuntu and i have some package that are told installable.how is it possible?i can even install gem

fenec@fenec-laptop:~$ gem
The program 'gem' can be found in the following packages:
 * rubygems1.8
 * rubygems1.9.1
Try: sudo apt-get install <selected package>
gem: command not found


root@fenec-laptop:/home/fenec# apt-get install rubygems1.8
Reading package lists... Done

Reading state information... Done
Package rubygems1.8 is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package rubygems1.8 has no installation candidate

Is it possible that some package are not installable due to my hardware? I have this problem only with this version of ubuntu i used to have ubuntu 8.10 and rails was working like a charm.

Answer 1

I usually install ruby gems from source. I would try following this guide - it's worked for me on multiple different Ubuntu installs.
