To address the errors and warnings encountered during the upgrade on Alpine ARM using the kairos-agent upgrade command, follow these steps:

1. Ensure Required Properties in Configuration:

   • The warning about missing properties ('users') indicates that the JSON schema validation requires a users section. Ensure your configuration includes this section:

     users:
     - name: "kairos"
     passwd: "kairos"

2. Check Installation State:

   • The warning about failing to read the installation state suggests that the state file /run/initramfs/cos-state/state.yaml is missing. Ensure that the state is mounted correctly at /run/initramfs/cos-state and is read-only:

     stateAssertVM(vm, "state.mounted", "true")
     stateAssertVM(vm, "state.mount_point", "/run/initramfs/cos-state")
     stateAssertVM(vm, "state.read_only", "true")
     <sup>[[1]](https://github.com/Itxaka/kairos/blob/master/tests/autoinstall_test.go)</sup>

3. Troubleshoot Mount Failures:

   • The mount failure (exit status 32) indicates an issue with mounting /dev/sda2 to /run/cos/state. Gather more information using the following diagnostic commands:

     df -h > /run/disk
     mount > /run/mounts
     blkid > /run/blkid
     dmesg > /run/dmesg.log

   • These commands will provide detailed information about disk usage, current mounts, block devices, and kernel messages, which are crucial for diagnosing mount failures ^[2].

4. Verify Partition Labels and Sizes:

   • Ensure that the partition labels and sizes specified in your configuration match the actual device labels and available space. Incorrect labels or insufficient space can cause mount failures:

     stages:
     boot:
      - name: "Repart image"
        layout:
          device:
            label: COS_RECOVERY
          add_partitions:
            - fsLabel: COS_STATE
              size: 16240 # At least 16gb
              pLabel: state

By following these steps, you should be able to resolve the errors and warnings encountered during the upgrade process on Alpine ARM using the kairos-agent upgrade command.
