If you are like  me using ubuntu 10 10  amp  cant find the lastest version which is now    ruby1 9 3   this is where you can get it http   www ubuntuupdates org package brightbox ruby ng experimental maverick main base ruby1 9 3  or download the   deb file      amp  remember that it wont alter you old version of ruby

Generally the verions of programs are linked to the version of your operating system  So if you were running gutsy you would either have to upgrade to the new jaunty jackalope version which has ruby 1 9 or add the respoistories for jaunty to your  etc apt sources list file  Once you have done that you can start up the synaptic package manager and you should see it in there

sudo apt-get install ruby1 9   should do the trick   You can find what libraries are available to install by   apt-cache search  lt your search term gt    So I just did apt-cache search ruby   grep 9 to find it   You ll probably need to invoke the new Ruby as ruby1 9  because Ubuntu will probably default to 1 8 if you just type ruby

Ruby is v2 0 now  Programs like Jekyll  and I am sure many others  require it  I just ran   sudo apt-get install ruby2 0  check version  ruby --version   Hope that helps

First  which version of ubuntu are you using  it might be easiest to just upgrade to one that has it   Next  enable backports  system menue  adminstration  software sources   and search for in in synaptic   Last  look for a ppa for it

There s really no reason to remove ruby1-8  unless someone else knows better  Execute the commands below to install 1 9 and then link ruby to point to the new version   sudo apt-get install ruby1-9 rubygems1-9 sudo ln -sf  usr bin ruby1-9  usr bin ruby

the above is not bad  however its kinda different for 11 10  sudo apt-get install ruby1 9 rubygems1 9   that will install ruby 1 9  when linking  you just use ls  usr bin   grep ruby it should output ruby1 9 1  so then you sudo ln -sf  usr bin ruby1 9 1  usr bin ruby and your off to the races

On Ubuntu 12 04  Precise Pangolin   I got this working with the following command   sudo apt-get install ruby1 9 1 sudo apt-get install ruby1 9 3

The author of this article claims that it would be best to avoid installing Ruby from the local packet manager  but to use RVM instead   You can easily switch between different Ruby versions   rvm use 1 9 3   etc
