Hello, I was trying to install CentOS-5.5-i386-bin-DVD tonight and kept on getting this same error and i have no idea what is causing this annoyance and not letting me complete the install because as soon as this error is produced it says this a bug and should be filed. Before I file a bug report i would like to know if anyone else ran into this and would mind pointing me in the right direction or a link to the solution. The full output is: http://pastebin.com/eEYZigrz i am hoping someone would be able to help, because i have no clue what is going on except that it is failing on trying to remove a volume group. Thanks Steven
