rEFInd failing in El Capitan MacBookPro5,3

I am continuing in my quest to dual-boot 10.04.3 Ubuntu.

I am tying to run rEFInd on OSX 10.11 and it is failing.

I am a little rusty on scripts - I did not change ANYTHING in the script.

Here is wha I got in terminal in my Downloads/refind-0.9.2 directory:

elliscmacpro:refind-bin-0.9.2 cartyellis$ ./install.sh
Not running as root; attempting to elevate privileges via sudo....
Password:
ShimSource is none
Installing rEFInd on OS X....
Installing rEFInd to the partition mounted at /Volumes/ESP
Found rEFInd installation in /Volumes/ESP/EFI/refind; upgrading it.
Copied rEFInd binary files


Notice: Backed up existing icons directory as icons-backup.
Existing refind.conf file found; copying sample file as refind.conf-sample
to avoid overwriting your customizations.


Could not set boot device property: 0xe00002bc


WARNING: If you have an Advanced Format disk, *DO NOT* attempt to check the
bless status with 'bless --info', since this is known to cause disk corruption
on some systems!!




ALERT:
Installation has completed, but problems were detected. Review the output for
error messages and take corrective measures as necessary. You may need to
re-run this script or install manually before rEFInd will work.
