<p>Depending on the AppGate SDP Server that is running, you may require a client that is more recent than the latest package on <a href=https://aur.archlinux.org/packages/appgate-sdp/>AUR</a>.
As of right now, the latest AUR is <code>4.2.2-1</code>.</p>
<p>These steps highlight how to get it working with <code>Python3.8</code> by making a 1 line modification to AppGate source code.</p>

<p>It turns out there are <a href=https://docs.python.org/3.7/library/platform.html#platform.linux_distribution>breaking changes</a> in Python3.8.</p>
<p>The docs that say <code>Deprecated since version 3.5, will be removed in version 3.8: See alternative like the distro package.</code></p>
<p>I guess this highlights one of the caveats of relying upon system python.</p>
