You may face this error while installing openvz web panel.
Fatal error: Panel requires Ruby 1.8 (Ruby 1.9 is not supported).
Fix:
# update-alternatives --config ruby
There are 2 choices for the alternative ruby (providing /usr/bin/ruby). Selection Path Priority Status ------------------------------------------------------------ * 0 /usr/bin/ruby1.9.1 51 auto mode 1 /usr/bin/ruby1.8 50 manual mode 2 /usr/bin/ruby1.9.1 51 manual mode Press enter to keep the current choice[*], or type selection number: 1 update-alternatives: using /usr/bin/ruby1.8 to provide /usr/bin/ruby (ruby) in manual mode
And rerun the installer:
wget -O - http://ovz-web-panel.googlecode.com/svn/installer/ai.sh | sh
