Upgrading OpenVPN VMWare Virtual Appliance
Upgrading is relatively easy because the OpenVPN Access Server is just a Debian package that runs on Ubuntu 14. Before upgrading OpenVPN it is a good idea to update the Ubuntu 14 server itself. You can use the standard:
apt-get update apt-get upgrade
Next, find the latest Ubuntu package from this page: https://openvpn.net/index.php/access-server/download-openvpn-as-sw/113.html?osfamily=Ubuntu. Copy the link for the Ubuntu 14 64-bit package. The current download for the 2.0.24 version is http://swupdate.openvpn.org/as/openvpn-as-2.0.24-Ubuntu14.amd_64.deb.
SSH into the appliance and run:
wget http://swupdate.openvpn.org/as/openvpn-as-2.0.24-Ubuntu14.amd_64.deb dpkg -i openvpn-as-2.0.24-Ubuntu14.amd_64.deb
This will upgrade the VMWare ESXi OpenVPN Virtual Appliance to the latest version.
