Postup končí chybou. Po chvíli hledání jsem našel příslušný bug report. ([#28372] require 'wxruby' failes on Ubuntu 10.04). Dále postupujeme například instalací opravených balíčků z repositáře Maria Steele podle [wxruby-users] New Debian/Ubuntu repository!. Začneme odinstalováním špatných gem balíčků.

# gem uninstall wxruby

# wget -q http://repo.trilake.net/apt/repo.gpg -O- | sudo apt-key add -
# sudo wget http://repo.trilake.net/apt/sources.list.d/lucid.list \
        -O /etc/apt/sources.list.d/trilake.list

# apt-get update
# apt-get install wxruby
