How can I fix the permissions to get rid of the following error and mount my USB and internal CD/DVD drive:
Adding read ACL for uid 1000 to `/media/bret' failed: Operation not supported
These drives worked fine in 12.04, but I apparently now don't have permissions to mount these drives in 12.10. I tried
chmod in the terminal, but I couldn't enter as the superuser, so I seem to be stuck. Please help!
