      Given a system administrator configuring DNS settings in a system,

      When they attempt to clear the DNS server settings stored in the interface by setting dns-resolver config to empty lists for search and server,

      Then NMState should successfully apply this change, resulting in the configured DNS servers being emptied as expected.

      Definition of Done:

      • The implementation meets the acceptance criteria
      • Unit test and integration test are written and pass
      • The code is part of a build attached to an errata

      What were you trying to do that didn't work?

      Failed to clean DNS server when stored in the interface using

      dns-resolver:
  config:
    search: []
    server: []

      While removing only `search` works, removing with

      dns-resolver:
  config: {}

      works too
       

       

      Please provide the package NVR for which bug is seen:
