Two of the Clarity PPM ISOs (DVD500000000002450.iso and DVD500000000002460.iso) generate the below error when attempting to mount. These files are needed to upgrade Clarity:

mount: wrong fs type, bad option, bad superblock on /dev/loop2,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so

Looking in the "dmesg" the below error is triggered for each:

ISOFS: Unable to identify CD-ROM format.


Component: PPMENV


Remove -t iso9660 from the command being used to mount the files that generate the errors. Two examples of commands that have worked for the above ISOs

sudo mount -o loop=/dev/loop2 DVD500000000002450.iso /opt/app/clarity/software/15_6/2450 
sudo mount -o ro,loop,dev DVD500000000002460.iso /opt/app/clarity/software/15_6/2460
