I have tried many include sudo apt-get purge ruby, sudo apt-get remove rubyand sudo aptitude purpe ruby, both with and without '*' at the end. But none of them worked, it's may be I've installed more than one version ruby.
我尝试了很多 include sudo apt-get purge ruby, sudo apt-get remove rubyand sudo aptitude purpe ruby，最后都有和没有 '*' 。但是它们都不起作用，可能是我安装了多个版本的 ruby。
Finally, when I triedsudo apt-get purge ruby1.9(with the version), then it works.
最后，当我尝试sudo apt-get purge ruby1.9（使用版本）时，它起作用了。

On Lubuntu, I just tried apt-get purge ruby* and as well as removing ruby, it looks like this command tried to remove various things to do with GRUB, which is a bit worrying for next time I want to reboot my computer. I can't yet say if any damage has really been done.
在 Lubuntu 上，我只是尝试了 apt-get purge ruby 以及删除 ruby，看起来这个命令试图删除与 GRUB 相关的各种事情，这对于下次我想重新启动计算机时有点担心。我还不能说是否真的造成了任何损害。

Then, use the uninstall command:
然后，使用卸载命令：

for example:
