You have to download* 'SHA1SUM' *and *'SHA256SUM'* files from the same directory with ISOs, and then you may check the integrity with the following commands: * *$ sha1sum -c SHA1SUM and $ sha256sum -c SHA256SUM (you should see positive checking results with the files you have downloaded.) --- wbr, Denis.
