Follow below steps to convert Ubuntu 20.04 with DCA-Enabler 1.5.0-14 to ThinOS 2205 (9.3.1129):

Prerequisites
- If you have a Latitude 3420 device that is running Ubuntu 20.04 operating system, ensure that DCA-Enabler 1.5.0-14 is installed.
- The Latitude 3420 device must have a factory-installed Ubuntu 20.04 operating system. If you have custom installed the Ubuntu operating system, you cannot convert it to ThinOS 2205.
- Wyse Management Suite version 3.7 must be used to convert to ThinOS 2205.
- Ensure that you have connected the Latitude 3420 device to the external power source using the power adapter.
- Ensure you have enough ThinOS Activation devices licenses on Wyse Management Suite 3.7
- Create a group in Wyse Management Suite with a group token.
- The ThinOS Activation devices license number of Wyse Management Suite must be larger than the Latitude 3420 device number. If not, you cannot create the Advanced Policy for conversion.
- The Latitude 3420 Ubuntu 20.04 devices must be registered to Wyse Management Suite as generic clients.
- Ensure you have downloaded the Ubuntu 20.04 to ThinOS 2205 conversion image.
- Extract the Ubuntu 20.04 to ThinOS 2205 conversion image to get the Conversion Installer file DTOS_Ubuntu_Installer_1.0-dtos14-amd64_signed.tar.gz and ThinOS image ThinOS_2205_9.3.1129.pkg.
