summary: Ensure that netplan config integration works
details: |
Check the netplan configuration is correct in Ubuntu Core 20+. Verify
that is is possible to add a br54 interface via netplan, including the
configuration for dhcp4 and dhcp6. Verify that `snap unset` works for the whole
br54 subtree
# TODO: enable for all ubuntu core versions once netplan.io got SRUed
# into the older versions of ubuntu
systems:
- ubuntu-core-2*
