How to upgrade ruby to the latest version in ubuntu?

@ubuntu:~$ ruby -v
ruby 1.9.3p194 (2012-04-20 revision 35410) [x86_64-linux]
@ubuntu:~$

I am using Ubuntu 12.10. Can it be upgraded to the latest version of
ruby?

when I installed it I didn’t use the rvm, I used the bellow command:

sudo apt install ruby

you can use brightbox’s ppa
refer to this link: http://wiki.brightbox.co.uk/docs:ruby-ng
or:

or: http://docs.brightbox.com/ruby/ubuntu/

no ruby 2.0 yet though…

Thanks for your suggestions.

I wanted to know why the version ‘Ruby 1.9.3-p392’ has not been updated
while I used the below?

sudo apt-get install ruby1.9.3

the above installed the version : “ruby 1.9.3p194”

I guess, p194 was the current version when 12.10 was released. You’ll
only get security updates for your
packages (if the maintainer takes care about this). If you want to get
the latest version automatically, you
should not use release-based linux distros (like debian,ubuntu, rh,…).
It’s not the philosophy behind
releases, that you’ll get bleeding edge versions for everything. I’m
using archlinux for several years now,
which has a rolling (i.e. no) release cycle - it’s not perfectly stable,
but I always get the latest version
for most of the packages, e.g. ruby:
https://www.archlinux.org/packages/extra/x86_64/ruby.

umm… i’m using that PPA, and my ruby version is:

$ ruby --version
ruby 1.9.3p327 (2012-11-10) [i686-linux] Brightbox

$ dpkg --list | grep ruby1.9
ii libruby1.9.1

i386 Interpreter of object-oriented scripting language Ruby
ii ruby1.9.1-dev

Should I need uninstall my existing one? If so Could you guide from
uninstallation to installation of “1.9.3p327” ?

maybe you should install brightbox’s ruby1.9.1

sudo apt-get install ruby1.9.1

$ apt-cache show ruby1.9.1 | grep Version
Version: 1:1.9.3.327-1bbox2~quantal1
Version: 1.9.3.194-1ubuntu1.3
Version: 1.9.3.194-1ubuntu1
