package ruby-rvm 1.6.9-0ubuntu2 failed to install/upgrade: subprocess installed post-installation script returned error exit status 2

[Ryan Jordan]

Attempted to install the package ruby-rvm on a mostly-fresh Ubuntu 12.04 (Beta) installation, by running this command:

$ sudo apt-get install ruby-rvm

This seems to be the relevant piece of the output:

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):
 subprocess installed post-installation script returned error exit status 2
Errors were encountered while processing:
 ruby-rvm
E: Sub-process /usr/bin/dpkg returned an error code (1)

Attempted to use rvm anyway:

ryan@incognito:~$ rvm
mkdir: cannot create directory `/usr/share/ruby-rvm/tmp': File exists
cat: /usr/share/ruby-rvm/README: No such file or directory
ryan@incognito:~$ groups
ryan adm cdrom sudo dip plugdev lpadmin sambashare
ryan@incognito:~$

Additional info:

ryan@incognito:~$ lsb_release -rd
