To convert the Ubuntu AB OTA, perform the following steps:
      
1. Change the system \_a and \_b partitions into one-system partition.
2. Change the abctl tool to adapt the one-system partition.
3. Delete the system upgrade content in the OTA package.
4. Gain the Debian packages, which use the APT to install in the Ubuntu. Zip them into the OTA package.
5. Update on-device upgrade script.
