I can not complete Sprint

[shupan]

Hi,

When a story is associated with a subtask (of type sub bug), it is always indicated that the current story has an incomplete subtask, regardless of which solution of the sub bug is selected to complete the Sprint.

Hi, @shupan Welcome to the Atlassian Community!

Can you please describe your questions clearly? 

If you have incomplete subtasks of stories then it will not consider as a complete story. When you will try to complete the sprint without completing the stories it will give you this message. You have the option to move back to incomplete stories back to the backlog or in the next sprint. You can choose any of these 2 options from the drop down.
