** Description changed:
+ [Impact]
+ All users of netplan.
+
+ [Test case]
+ 1) Write an invalid netplan yaml (for each of the examples below)
+ 2) Validate the error is as expected.
+ 3) Verify that the error matches refers to a meaningful place in file (check
line and column values).
+
+ == Error due to missing fields ==
+
+ network:
+ version: 2
+ ethernets:
+ engreen:
+ routing-policy:
+ - table: 50
+ addresses:
+ - 192.168.14.2/24
+ - 2001:FFfe::1/64
+
+ Expected error:
+ """
+ /etc/netplan/01-network-manager-all.yaml:10:9: Error in network definition:

+ - table: 50
+ ^
+ """
+
+ == Syntax error: unsupported features ==
+
+ network:

+ engreen:
+ dhcp4: *yes

+
+ == Syntax error: use of tabs in config ==
+
+ network:
+ <tab>version: 2
+ <tab>renderer: NetworkManager
+
+ Expected error:
+ """
+ /etc/netplan/01-network-manager-all.yaml:3:1: Invalid YAML: tabs are not

+ """
+
+ == Unsupported mix of features ==
+
+ network:

+ mode: isatap
+ local: 1.1.1.1
+ remote: 2.2.2.2
+ addresses: [ 15.15.15.15/24 ]
+ gateway4: 20.20.20.21
+
+ Expected error:
+ """
+ /etc/netplan/01-network-manager-all.yaml:10:7: Error in network definition:
tun0: ISATAP tunnel mode is not supported by networkd
+ mode: isatap
+ ^
+ """
+
+ [Regression potential]
+ Minimal. Supported configurations remain unchanged. Users relying on
automated parsing of netplan error messages (would that be a thing?) will find
the messages have vastly changed. None of the strings are currently
translatable/translated.
+
+ ---
+
Give more information about the error, including its exact location in
the code.
Make the error messages shorter but still understandable.
Present clear context so people understand what we found was wrong, if
not from line/column number, then from the extract from their file, with
a marker to the error.
** Changed in: netplan
