    This looks like an issue with the PGP-signature of the ARCH package.
    We cannot help here. You'll need to ask the maintainers of the
    package:<br>
    <a class="moz-txt-link-freetext" href="https://www.archlinux.org/packages/extra/x86_64/cantor/">https://www.archlinux.org/packages/extra/x86_64/cantor/</a><br>
    <br>
    Alternatively, since you're going to compile from the sources
    anyway, you can 'git clone' Cantor's code from the official
    repository and compile it.<br>
    However, you'll need to manually install couple of devel-packages
    for the libraries used by Cantor...<br>
    <br>
    <br>
    Regards,<br>
    Alexander<br>
