[{"content":"AppGate SDP provides a Zero Trust network. This post describes how to get AppGate SDP 4.3.2 working on Arch Linux.\nDepending on the AppGate SDP Server that is running, you may require a client that is more recent than the latest package on AUR. As of right now, the latest AUR is 4.2.2-1.\nThese steps highlight how to get it working with Python3.8 by making a 1 line modification to AppGate source code.\nPackaging We already know the community package is out of date, so let\u0026rsquo;s clone it:\ngit clone https://aur.archlinux.org/appgate-sdp.git cd appgate-sdp You\u0026rsquo;ll likely notice that the version is not what we want, so let\u0026rsquo;s modify the PKGBUILD to the following:\n# Maintainer: Pawel Mosakowski \u0026lt;pawel at mosakowski dot net\u0026gt; pkgname=appgate-sdp conflicts=(\u0026#39;appgate-sdp-headless\u0026#39;) pkgver=4.3.2 _download_pkgver=4.3 pkgrel=1 epoch= pkgdesc=\u0026#34;Software Defined Perimeter - GUI client\u0026#34; arch=(\u0026#39;x86_64\u0026#39;) url=\u0026#34;https://www.cyxtera.com/essential-defense/appgate-sdp/support\u0026#34; license=(\u0026#39;custom\u0026#39;) # dependecies calculated by namcap depends=(\u0026#39;gconf\u0026#39; \u0026#39;libsecret\u0026#39; \u0026#39;gtk3\u0026#39; \u0026#39;python\u0026#39; \u0026#39;nss\u0026#39; \u0026#39;libxss\u0026#39; \u0026#39;nodejs\u0026#39; \u0026#39;dnsmasq\u0026#39;) source=(\u0026#34;https://sdpdownloads.cyxtera.com/AppGate-SDP-${_download_pkgver}/clients/${pkgname}_${pkgver}_amd64.deb\u0026#34; \u0026#34;appgatedriver.service\u0026#34;) options=(staticlibs) prepare() { tar -xf data.tar.xz } package() { cp -dpr \u0026#34;${srcdir}\u0026#34;/{etc,lib,opt,usr} \u0026#34;${pkgdir}\u0026#34; mv -v \u0026#34;$pkgdir/lib/systemd/system\u0026#34; \u0026#34;$pkgdir/usr/lib/systemd/\u0026#34; rm -vrf \u0026#34;$pkgdir/lib\u0026#34; cp -v \u0026#34;$srcdir/appgatedriver.service\u0026#34; \u0026#34;$pkgdir/usr/lib/systemd/system/appgatedriver.service\u0026#34; mkdir -vp \u0026#34;$pkgdir/usr/share/licenses/appgate-sdp\u0026#34; cp -v \u0026#34;$pkgdir/usr/share/doc/appgate/copyright\u0026#34; \u0026#34;$pkgdir/usr/share/licenses/appgate-sdp\u0026#34; cp -v \u0026#34;$pkgdir/usr/share/doc/appgate/LICENSE.github\u0026#34; \u0026#34;$pkgdir/usr/share/licenses/appgate-sdp\u0026#34; cp -v \u0026#34;$pkgdir/usr/share/doc/appgate/LICENSES.chromium.html.bz2\u0026#34; \u0026#34;$pkgdir/usr/share/licenses/appgate-sdp\u0026#34; } md5sums=(\u0026#39;17101aac7623c06d5fbb95f50cf3dbdc\u0026#39; \u0026#39;002644116e20b2d79fdb36b7677ab4cf\u0026#39;) Let\u0026rsquo;s first make sure we have some dependencies.
