[Bug 1804721] Re: netplan fails through to generic error handler when specifying bridge

 

Yes, absolutely. In fact, I fixed this already:

$ ~/bin/netplan --root-dir=scratch/ --debug generate
DEBUG:command generate: running ['/lib/netplan/generate', '--root-dir', 'scratch/']
** (generate:18683): DEBUG: 16:41:58.422: Processing input file scratch//etc/netplan/01-my_network.yaml..
scratch//etc/netplan/01-my_network.yaml:9:4: Invalid YAML: inconsistent indentation:
   bridges:
   ^


The changes are available in Ubuntu 19.04 already; will be made available to other releases soon as stable updates.

FWIW, the issue is one space too much before "bridges:". Sorry I
couldn't get to respond to this sooner!

Bug description:
  Ubuntu 18.04.1 LTS, Release:    18.04

  adding a specification for a bridge to /etc/netplan/01-my_network.yaml
  causes a fail-over to a catch-all exception handler. No useful
  debugging information is given. ( i wish you had markdown )

  $ sudo netplan try -debug 
  Error while loading /etc/netplan/01-my_network.yaml, aborting.

  the source file has contents:

  "
  # Let netplan manage all devices on this system
  network:
    version:        2
    renderer:       networkd
    ethernets:
      enp5s0:
        dhcp4:      yes
        dhcp6:      no

     bridges:
      lxdbr0:
        dhcp4:      yes
        interfaces:
          - enp5s0
  "

  It loads without error if the bridges section is removed. The file is a simple example from https://netplan.io/examples#bridging
  I have tried several other configurations, all fail when bridging is attempted.

  I believe the netplan source is at:
  https://github.com/CanonicalLtd/netplan/blob/master/netplan/configmanager.py

  I'm guessing the handler should not be activated.

          except (IOError, yaml.YAMLError):  # pragma: nocover (filesystem failures/invalid YAML)
              logging.error('Error while loading {}, aborting.'.format(yaml_file))
              sys.exit(1)
