I need to upgrade gems to 1.8 i tried installing the respective debian packages but it seems its not getting upgraded

run this commands as root or use sudo.
You can update all gems by just performing:
sudo gem update
Or:
gem update `gem outdated | cut -d ' ' -f 1`
I found other answers to be inaccurate/outdated. Best is to refer to the actual documentation.
Short version: in most cases gem update --system will suffice.
You should not blindly use sudo. In fact if you're not required to do so you most likely should not use it.
You can update gem to any specific version like this,
gem update --system 'version'
gem update --system '2.3.0'
For me it sufficed to simply run
gem update
I wouldn't use the debian packages, have a look at RVM or Rbenv.
To update just one gem (and it's dependencies), do:
bundle update gem-name
But to update just the gem alone (without updating it's dependencies), do:
bundle update --source gem-name
If you're using RVM, the command below helped me a lot when upgrading from a very very old rubygems (eg 1.3.7) that defies the more current update commands mentioned in the other responses in this thread.
rvm rubygems <version>

What is the difference between this command:
gem update --system
And these commands:
gem install rubygems-update
update_rubygems
gem update --system
I would've assumed that the former would be all that is required in order to update to the latest version of RubyGems, but I have found many references (including https://stackoverflow.com/a/13626200/1369417) which recommend the latter.
gem install rubygems-update; update_rubygems was needed in some old versions of rubygems, but gem update --system is all that's needed for the foreseeable future.
rubygems 1.1 and 1.2 had bugs that prevented gem update --system from working the first time, so you had to use those first two commands to upgrade at all. There would be no reason to run gem update --system immediately thereafter, because rubygems would already be updated, but doing so would demonstrate that you would be able to run that command in the future.
Versions of rubygems before 1.5.2 did not accept a version argument following gem update --system, so you had to use the first two commands you give to install an arbitrary version of rubygems. You wouldn't want to run gem update --system immediately thereafter; it would undo what you'd just done.
More here: https://github.com/rubygems/rubygems/blob/master/UPGRADING.md
When I execute both , apparent difference is:
update_rubygems - update gem to the current update_rubygems version.
gem update --system (without version option) - update to latest version.
For example, when the following situations:
gem: 3.0.6
update_rubygems: 3.2.17
latest gem: 3.3.8
then,
$ sudo update_rubygems --no-document
...
$ gem -v
3.2.17
while
$ sudo gem update --system --no-document
...
$ gem -v
3.3.8
That's current result as of today.
I had rubygems 1.3.5 (or 1.3.6?) installed and then made a sudo gem update after a long while again. Some gems complained they needed a newer gems version. Because sudo gem update --system is deactivated on Ubuntu I followed these steps: How can I get RubyGems 1.3.6 on Ubuntu 10.4
But now I cannot start the dev_appserver.rb anymore, it says:
=> Bundling gems
ERROR: While executing gem ... (RuntimeError)
Unknown command bundle
I also tried to do sudo gem update and sudo gem update --system again a few times but everything is up-to-date now. Here is a list of my gems: http://pastebin.com/cFaTCyF5
It's a bit of a hack around but I can't really tell what's going on properly from what you sent but I know a few people have been having problems after running gem update --system lately. Find out what version you've just installed with
gem list
Look for the update, should look something like this: rubygems-update-1.5.0
Then try rolling back your rubygems version
sudo gem uninstall rubygems-update -v 1.5.0
sudo gem install rubygems-update -v 1.4.2 <-- try a different version
gem install --system 1.3.7 worked in my case
Trying to install the 'less' gem. I type sudo gem install less as instructed at http://lesscss.org/, and I get the following error:
ERROR: While executing gem ... (Gem::GemNotFoundException)
Could not find less (> 0) in any repository
Alright, so I figure maybe I just need to update RubyGems. Trying 'gem update --system' gets me
Updating RubyGems...
Attempting remote update of rubygems-update
ERROR: While executing gem ... (Gem::InstallError)
rubygems-update requires builder >= 0
Arrgh. Alright, then let's try 'sudo gem install builder':
ERROR: While executing gem ... (Gem::GemNotFoundException)
Could not find builder (> 0) in any repository
Seems that no matter what gem I try to install, it can't be found in any repository. I check my environment, and rubyforge is listed:
RubyGems Environment:
- VERSION: 0.9.4 (0.9.4)
- INSTALLATION DIRECTORY: /usr/local/lib/ruby/gems/1.8
- GEM PATH:
- /usr/local/lib/ruby/gems/1.8
- REMOTE SOURCES:
- http://gems.rubyforge.org
Any idea what's going on? I'm on OSX 10.4, and I installed Ruby 1.8.6 before this.
I think rubygems 1.3.x requires ruby 1.8.7 so you might install that first. Then update rubygems to 1.3.7. via gem update --system
The version of rubygems bundled in osx uses gemforge as its offical source of gems - this has since been replaced with gemcutter. You should be able to do
sudo gem update --system
To upgrade to update the latest version of ruby gems, which will then use gemcutter as the sources link
That's a really old version of rubygems! How did you install this?
Is it a manual install? If so, perhaps you could try a manual upgrade the same way.
Do the following:
sudo gem update --system
to update your install of RubyGems. Then, add the Github gem repository to your sources. I suggest github because you'll find a lot of useful things there:
sudo gem sources -a http://gems.github.com
I'm trying to install the thinking sphinx gem, which is on gemcutter.org
When I run the command
gem sources -a http://gemcutter.org
I get the error:
Error fetching http://gemcutter.org:
bad response Not Found 404 (http://gemcutter.org/specs.4.8)
If I change the above URL to http://gemcutter.org.specs.4.8.gz it finds a file. How do I tell rubygems to download with the .gz extension?
It looks like a temporary Gemcutter failure. It works fine to me.
Make sure you are running the latest RubyGems version and install the latest gemcutter gem.
$ gem install gemcutter --source http://gemcutter.org
With the gemcutter GEM you type gem tumble to add Gemcutter as source.
$ gem tumble
EDIT. I just noticed you are using a really outdated RubyGems version.
Update RubyGems first.
$ gem update --system
If it tells you there's nothing to update, you have a buggy version (RubyGems 1.2 selfupdate was buggy). Upgrade with the following command.
$ gem install rubygems-update
$ update_rubygems
Then add the source.
What version of Rubygems are you running (gem --version)? If less than 1.3.5, you may want to update Rubygems and try again. (gem update --system)
This is working for me with the following sources defined:
http://gems.rubyforge.org/
http://gems.github.com
as I said this is working for me:
gem install thinking-sphinx \
> --source http://gemcutter.org
If you're upgrading, you should read this:
http://freelancing-god.github.com/ts/en/upgrading.html
Successfully installed thinking-sphinx-1.3.2
Successfully installed activesupport-2.3.4
2 gems installed
Installing ri documentation for thinking-sphinx-1.3.2...
Installing ri documentation for activesupport-2.3.4...
Why is the following happening, and how can I sort it?
On OS X Leopard (v10.5.6):
$ ./script/server
Rails requires RubyGems >= 1.3.1 (you have 1.2.0). Please `gem update --system` and try again.
$ sudo gem update --system
Updating RubyGems
Nothing to update
I haven't hit this issue myself but I've seen this as a possible solution:
$ sudo gem install rubygems-update
Successfully installed rubygems-update-1.3.0
1 gem installed
$ sudo update_rubygems
This should let you install the updating via the specific updater gem.
