netplan-try - try a configuration, optionally rolling it back

                                                                                                  NETPLAN-TRY(8)

netplantry  takes  a  netplan(5) configuration, applies it, and automatically rolls it back if the user
       does not confirm the configuration within a time limit.

       A configuration can be confirmed or rejected interactively or by sending the SIGUSR1 or SIGINT signals.

       This may be especially useful on remote systems, to prevent an administrator being permanently locked out
       of systems in the case of a network configuration error.

netplantry uses similar procedures to netplanapply, so some of the same caveats  apply  around  virtual
       devices.

       There  are  also  some  known  bugs: if netplantry times out or is cancelled, make sure to verify if the
       network configuration has in fact been reverted.

       As with netplanapply, a reboot should fix any issues.  However, be sure to verify that the configuration
       on disk is in the state you expect before rebooting!

       -h, --help
              Print basic help.

       --debug
              Print debugging output during the process.

       --config-file CONFIG_FILE
              In addition to the usual configuration, apply  CONFIG_FILE.   It  must  be  a  YAML  file  in  the
              netplan(5) format.

       --timeout TIMEOUT
              Wait  for  TIMEOUT  seconds  before  reverting.   Defaults to 120 seconds.  Note that some network
              configurations (such as STP) may take over a minute to settle.
