ValueError: 'Undone' is not a valid TaskStatus
According to snapd's upstream repository, "Undone" existed before
"Undoing", so I'm not sure why we didn't have the former but had the
latter. Maybe we just overlooked it because the name is similar.
As for more recently, the "Wait" status was also introduced.
Fixed by adding the two missing values (i.e., "Wait" and "Undone").

This is one of the pain points of using the style of serialization for enums subiquity uses for an API we do not 100% control. Maybe there should be a way to say that a field can be an enum but if the value seen does not match one of the values of the enum type, just include it as a string or something? |

That said again... what should subiquity do in the case that it sees an Undone change? That's probably a terminal status, right? |
Good question, I have to check what the Undoing / Undone logic means in the snap refresh context.. |
