    <p>Most likely, the verification failed because of an error
    or interruption during the download.</p>

    <p>The verification also fails if you try to verify a different
    download than the latest version, Tails [[!inline pages="inc/stable_amd64_version" raw="yes" sort="age"]].</p>

    <p>Less likely, the verification might have failed because
    of a malicious download from our download mirrors or due to
    a network attack in your country or local network.</p>

    <p>Downloading again is usually enough to fix this
    problem. Otherwise, please try downloading from a different place or a
    different computer.</p>
