      Aptosid manual wrote:
Download the following files from the mirror:

MD5SUM
MD5SUM.gpg
SHA256SUM
SHA256SUM.gpg

In a terminal:

$ md5sum aptosid.iso

If they don't match, you will get an error:

"aptosid.iso: Error
md5sum: Warning: calculated checksum does not match!"

If the downloaded file is correct, the program ends without a message.

The manual seems incorrect about this, in multiple languages. The md5sum or sha256sum commands issued like this will only output the checksum and not show if it's correct or not:
      Code:
$ md5sum aptosid-2011-03-ponos-kde-lite-amd64-201112312100.iso
ab7b8287ace979794ae3fb97ce6972aa  aptosid-2011-03-ponos-kde-lite-amd64-201112312100.iso
$ sha256sum aptosid-2011-03-ponos-kde-lite-amd64-201112312100.iso
ab80523b2923535ca78f9e5322c77abec7bc262ce1f49e32208459f9d6d486b7  aptosid-2011-03-ponos-kde-lite-amd64-201112312100.iso

The command that I know of to compare the checksums is this:
      Code:
md5sum -c MD5SUM
md5sum: aptosid-2011-03-ponos-kde-full-i386-amd64-201112312100.iso: No such file or directory
aptosid-2011-03-ponos-kde-full-i386-amd64-201112312100.iso: FAILED open or read
aptosid-2011-03-ponos-kde-lite-amd64-201112312100.iso: OK
...

I came across this again after I just had a bad checksum on this iso and had to download it again.
