ubuntu-core-upgrader

Tools to apply a new system image to a running Ubuntu Core system

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.
