PROGRAM:

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.
