How can I solve this error?
sudo apt-get update
sudo apt-get install ruby1.8-dev
sudo apt-get install mysql-server
sudo apt-get install libgemplugin-ruby
Currently I am getting this error:
sudo apt-get install ruby1.8-dev

Package ruby1.8-dev is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or is only available from another source
E: Package 'ruby1.8-dev' has no installation candidate
