need installation support on Fatal error: Panel requires Ruby 1.8 (Ruby 1.9 is not supported).

When installer stops do next: 2. ruby -v (output will be probably ruby1.9.1...) 1. apt-get install ruby-switch 3. ruby-switch --list (output - all installed ruby versions -> ruby1.8 & ruby1.9.1) 4. ruby-switch --set ruby1.8 5. ruby -v (output -> ruby 1.8.7 (2012-02-08 patchlevel 358) [x86_64-linux]) 6. run installer again #./ai.sh
