NAME
       ubuntu-core-upgrade - apply an Ubuntu Core system image to a running system


SYNOPSIS
       ubuntu-core-upgrade [OPTIONS]...  command-file


DESCRIPTION
       This command, which is generally configured to be called by system-image-cli(1) applies the latest Ubuntu
       Core system image to the running system.

       The argument  command-file  should  specify  the  full  path  to  the  declarative  script  generated  by
       system-image-cli(1) listing all steps required for the upgrade.


OPTIONS
       --check-reboot
              Attempt to determine if a reboot may be required.

              This option is similar to --dry-run: no system changes are made.

              Note  that  the result of this command cannot be definitive since a reboot would be triggered if a
              service failed to start (but this option does not attempt to restart any services).

       --clean-only
              Clean up from a previous upgrader run, but do not upgrade.

       --debug
              Enable debug output.

       --dry-run
              Do not actually apply the update - simulate what would happen.

       --force-inplace-upgrade
              Apply an upgrade to current rootfs even if running on dual rootfs system (for testing).

       -h, --help
              Display usage.

       --leave-files
              Do not remove the downloaded system image files after upgrade.

       --no-reboot
              Do not reboot even if one would normally be required.

       --reboot-delay=seconds
              Wait for specified number of seconds before rebooting (default=2).

       --root-dir=directory
              Specify an alternative root directory (for testing).

       --show-other-details
              Dump the details of the system-image vesion on the other root partition.

       --tmpdir=directory
              Specify a alternate, pre-existing temporary directory to use.


NOTES
       If invoked without --check-reboot and without --debug, output will be sent to standard error and syslog.


WARNING
       This script should not be invoked directly by a user or administrator.
