I'm a newbie of emacs and I followed the guide from this web step by step.
But when it startup, it said
Warning (initialization): An error occurred while loading `/home/mrfive/.emacs.d/init.el':
error: Package `color-theme-' is unavailable
To ensure normal operation, you should investigate and remove the cause of the error in your initialization file. Start Emacs with the `--debug-init' option to view a complete error backtrace.
what should I do now? Thank?
