ruby gem update system is disabled on Debian

Problem:

ERROR:  While executing gem ... (RuntimeError)
    gem update --system is disabled on Debian. RubyGems can be updated using the official Debian repositories by aptitude or apt-get.

Unfortunately the apt-get update does not help at all.

Solution:

gem install update_rubygems
cd /var/lib/gems/1.8/bin
./update_rubygems

or

gem install rubygems-update
cd /var/lib/gems/1.8/bin
./update_rubygems

    If you’re following this guide, and you get a message like “Could not find RubyGem builder”, try installing an older version of update_rubygems. I could not get 1.3.5 to work, but 1.3.4 worked fine on a Debian Lenny machine.

    gem install update_rubygems –version=1.3.4
    cd /var/lib/gems/1.8/bin
    ./update_rubygems
