Could you please upload your /etc/fstab file? Maybe when the cdrom is mounted, it is mounted with the wrong permissions.
You can try to remount the cdrom with the correct permissions - check the man page for mount for details. ** Changed in: Ubuntu Status: Unconfirmed => Needs Info -- Insert CD -- mounts with all file permissions -rwx------ https://launchpad.net/bugs/72872 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
