I'm trying to upgrade my Mid 2014 Macbook pro from OSX Yosemite to El Capitan GM Beta. I have downloaded update today but while upgrading, installation stops and throws the following error.

OS X could not be installed on your computer

This core storage operation is not allowed on a sparse logical volume group. Quit the installer to restart your computer and try again.

Anybody know how to fix this error?

Your help much appreciated.

After many researches on Apple technical forum, I found that one of the possible cause for the error

This core storage operation is not allowed on a sparse logical volume group. Quit the installer to restart your computer and try again

is FileVault encryption incompatibilities. I looked up in my Macbook for FileVault settings, the FileValt was turned off in my machine. I Enabled FileVault encryption and tried OSX El Capitan upgrade again. This time installation completed without any error.

This solution worked fine for me.
