       system-image-cli - Ubuntu System Image Upgrader command line script


       system-image-cli [options]


       This  script  upgrades the system to the latest available image (i.e. build number).  With
       no options, this script checks the latest version available on the server  and  calculates
       an  upgrade path to that version from the system's current version.  If an upgrade path is
       found, the relevant files are downloaded and the  upgrade  is  applied  by  rebooting  the
       system into recovery mode.


       -h, --help
              Show the program's message and exit.

              Show the program's version number and exit.

       -b NUMBER, --build NUMBER
              Override  the  device's  current  build  number  just this once.  NUMBER must be an
              integer.  Use -b 0 for force an upgrade.

       -c CHANNEL, --channel CHANNEL
              Override the device's upgrade channel just this  once.   Use  in  combination  with
              --build 0 to switch channels.

       --switch CHANNEL
              This  is  a  convenience  alias  for  the combination of -b 0 -c CHANNEL.  It is an
              easier way to switch channels.  If -switch is given with -b and/or -c,  the  latter
              take precedence.

              Lists the available channels, including aliases, and exits.

       -d DEVICE, --device DEVICE
              Override the device name just this once.

       -f FILTER, --filter FILTER
              Filter  the  candidate upgrade paths to only contain full or delta updates.  FILTER
              must be either full or delta.

       -m IMAGENO, --maximage IMAGENO
              Cap a winning upgrade path to image number IMAGENO.   All  images  with  a  version
              number  greater  than IMAGENO will be ignored.  For example, if the winning upgrade
              path is 200:204:304 and you give -m 205, the upgrade will not include image  number
              304.  Note that this capping happens after the winning upgrade path is selected.

       -i, --info
              Show some information about the current device, including the current build number,
              device name, and channel, then exit.

       -n, --dry-run
              Calculate and print the upgrade path, but do not download  or  apply  it.   New  in
              system-image 2.5.1: output displays the target phase percentage

       -p VALUE, --percentage VALUE
              For  testing purposes, force a device specific phase percentage.  The value must be
              an integer between 0 and 100.  New in system-image 2.5.1

       -g, --no-apply
              Downloads all files and prepares for, but does not actually apply the  update.   On
              devices which require a reboot to apply the update, no reboot is performed.

       -v, --verbose
              Increase  the  logging  verbosity.   With  one  -v,  logging goes to the console in
              addition to the log file, and logging at INFO level is enabled.  With  two  -v  (or
              -vv), logging both to the console and to the log file are output at DEBUG level.

       -C DIR, --config DIR
              Use  the  given  configuration  directory,  otherwise  use the system default.  The
              program will read all the files  in  this  directory  that  begin  with  a  number,
              followed  by  an  underscore, and ending in .ini (e.g. 03_myconfig.ini).  The files
              are read in sorted numerical order from lowest prefix number to highest, with later
              configuration files able to override any variable in any section.

              Wipes  the  data  partition  and  issues  a reboot into recovery.  This effectively
              performs a device factory reset.

              Show all the key/value pairs in the settings database.

       --progress [dots|logfile|json]
              Report progress in various ways.  dots prints some dots every once in  a  while  to
              stderr; this mimic what was available in system-image 2.5.  logfile prints messages
              at debug level to the system-image log file, and is also available in 2.5 (via  the
              --verbose flag).  json prints JSON records to stdout.  New in system-image 3.0

       --get KEY
              Print the value for the given key in the settings database.  If the key is missing,
              a default value is printed.  May be given multiple times.

       --set KEY=VALUE
              Set the value for the given key in the settings database.  If the key is missing it
              is added.  May be given multiple times.

       --del KEY
              Deletes  the given key from the settings database.  If the key does not exist, this
              is a no-op.  May be given multiple times.

              Allows an update to proceed while the device is on GSM and currently  set  to  only
              use  wifi.   This  is  only  effective  when using ubuntu-download-manager.  New in
              system-image 3.1.
