when i try to install ruby-rvm in ubuntu 12.04 using this command
sudo apt-get install ruby-rvm
it downloads the packages correctly but then gives this error
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:
E: Sub-process /usr/bin/dpkg returned an error code (1)
the contents of stateoverride file are as follows
root mlocate 2755 /usr/bin/mlocate
hplip root 755 /var/run/hplip
root ssl-cert 710 /etc/ssl/private
root crontab 2755 /usr/bin/crontab
any help would be appreciated
