Ubuntu 8.10 Downgrade Ruby 1.8.7 to 1.8.6
As you may know Ruby 1.8.7 don't compatable with Rails(http://www.rubyonrails.org/down)
We recommend Ruby 1.8.6 for use with Rails. Ruby 1.8.7, 1.8.5, 1.8.4 and 1.8.2 are still usable too, but version 1.8.3 is not. Ruby 1.8.7 still has some bugs to straighten out.
Step-by-step to downgrade Ruby to 1.8.6
1) Replace /etc/apt/sources.list file with follow data:

2) Create new file /etc/apt/preferences
Package: ruby Pin: release a=hardy Pin-Priority: 900 Package: ruby1.8 Pin: release a=hardy Pin-Priority: 900 Package: libruby1.8 Pin: release a=hardy Pin-Priority: 900 Package: rdoc1.8 Pin: release a=hardy Pin-Priority: 900 Package: ri1.8 Pin: release a=hardy Pin-Priority: 900 Package: libgtk2-ruby1.8 Pin: release a=hardy Pin-Priority: 900 Package: libdbd-sqlite3-ruby1.8 Pin: release a=hardy Pin-Priority: 900 Package: libopenssl-ruby1.8 Pin: release a=hardy Pin-Priority: 900 Package: libsqlite3-ruby1.8 Pin: release a=hardy Pin-Priority: 900 Package: ruby1.8-dev Pin: release a=hardy Pin-Priority: 900 Package: libdbi-ruby1.8 Pin: release a=hardy Pin-Priority: 900 Package: libatk1-ruby1.8 Pin: release a=hardy Pin-Priority: 900 Package: libpango1-ruby1.8 Pin: release a=hardy Pin-Priority: 900 Package: libatk1-ruby1.8 Pin: release a=hardy Pin-Priority: 900 Package: libgdk-pixbuf2-ruby1.8 Pin: release a=hardy Pin-Priority: 900 Package: libglib2-ruby1.8 Pin: release a=hardy Pin-Priority: 900 Package: libcairo-ruby1.8 Pin: release a=hardy Pin-Priority: 900 Package: irb1.8 Pin: release a=hardy Pin-Priority: 900 Package: libreadline-ruby1.8 Pin: release a=hardy Pin-Priority: 900 Package: rails Pin: release a=hardy Pin-Priority: 900 Package: libncurses-ruby1.8 Pin: release a=hardy Pin-Priority: 900
3) Open synaptic and find "ruby" relate packages (just search "ruby"). Check for completly removal installed packages (3-7 installed packages will be here)
4) sudo apt-get update
5) sudo apt-get install ruby rdoc irb libyaml-ruby libzlib-ruby ri libopenssl-ruby ruby1.8-dev build-essential
That's all :)

Many thanks. I have had problems for more than a week now, finally figured out it was 1.8.7. My sanity will be much improved.
