After upgrading my Ubuntu 14.10 to 15.04 my Rmagick gem is not working in any application with a specific version then first i remove the version of rmagick gem inside the Gemfile of rails application and then i install first imagemagick .

After install imagemagick install package of imagemagick for install Rmagick gem by this command.

2. sudo apt-get install libmagickwand-dev


Now ! first exit the rails directory then again goto rails directory and run the bundle command. ;)
