what is the best approach to unlock and clean this?
It appears that the snapshot has never finished finalizing. How old is the snapshot (or how bust is the VM)? The user experience here is bad, but I'm wondering whether the task is actually still running... I'll look at engine.log The task is still running. Let's see if we can block the operation later, once there's capacity This bug didn't get any attention for a while, we didn't have the capacity to make any progress. If you deeply care about it or want to work on it please assign/target accordingly This bug didn't get any attention for a while, we didn't have the capacity to make any progress.
