apt will remove debian-maintainers, but I don’t think this package is neccesary.
change your /etc/apt/sources.list back to its original contents.
Change back to your normal user.
Now you can verify the images by first downloading the iso-file and the corresponding SHA512SUMS and SHA512SUMS.sign files from the same directory (for 64bit PC: http://cdimage.debian.org/debian-cd/6.0.0/amd64/iso-cd/).
The warning may be safely ignored because apt cryptographically verifies all packages and the keyring file debian-role-keys.gpg was installed by apt.
You can ignore the „FAILED open or read“ lines – sha512sum just looks for all cd images listed in the file. The „OK“ line must be there.
Now you have successfully verified the ISO – have fun installing!
