** Description changed:
- Hello.
+ [Impact]
+ Any Netplan user leaving empty files in /etc/netplan.
- We see on our jenkins some failing tests on machines updated with the
- bionic-proposed repository.
-
- We found that netplan is crashing when there is an empty YAML
- configuration file.
-
- To reproduce:
+ [Test case]
1) put a valid configuration under /etc/netplan/
2) create an empty YAML file /etc/netplan/99-empty.yaml
3) execute netplan apply
+
+ Validate that 'netplan apply' does not crash, and correctly applies the
+ configuration.
+
+
+ [Regression potential]
+ Watch out for issues in merging netplan configuration or evaluating the parts
of configuration that can't be reverted safely, for the use of 'netplan try'.
