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

## SYNOPSIS
       **netplan** [--debug] **try** -h | --help

       **netplan** [--debug] **try** [--config-file _CONFIG_FILE_] [--timeout _TIMEOUT_]

## DESCRIPTION
       **netplan**  **try** takes a [**netplan**(5)](https://www.chedong.com/phpMan.php/man/netplan/5/markdown) 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  SIG‐
       INT signals.

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

## OPTIONS
### -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)](https://www.chedong.com/phpMan.php/man/netplan/5/markdown) 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.

## KNOWN ISSUES
       **netplan** **try** uses similar procedures to **netplan** **apply**, so  some  of  the  same  caveats  apply
       around virtual devices.

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

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