在使用 RVM 安装 Ruby1.9.3 时 rvm install 1.9.3，它显示以下消息。
The program 'rvm' is currently not installed. You can install it by typing:
sudo apt-get install ruby-rvm
之后我尝试安装 ruby-rvm 但它最后显示以下消息。
...
Setting up libreadline-gplv2-dev (5.2-11) ...
Setting up ruby-rvm (1.6.9-0ubuntu2) ...
dpkg-statoverride: error: syntax error: unknown group 'admin' in statoverride file
dpkg: error processing ruby-rvm (--configure):

Errors were encountered while processing:
ruby-rvm
E: Sub-process /usr/bin/dpkg returned an error code (1)
收到此消息后，我在此处查看，但无法弄清楚上述错误代码的含义。

我曾尝试安装它并浪费了 3 天，但无法成功在 Rails 上安装 ruby 并解决上述错误。由于我是 ruby 新手，因此感谢任何帮助。
