Comment 1 for bug 1873271

I would also like to add that the bug seems to be related to everything I do on the network-data.yaml. Originally I had only messed a bit with the Management network . And the upgrade command failed. After making a change the other parts of the yaml (lets say the external netowrk). Then the installer throws an error for that network as well! If then I revert that exact change, then then the bug remains! and Basically I cannot edit my network file
