 ## Problem
 
+I am experiencing issues while deleting objects
+
 ## Cause
 
+object is locked
+bucket is versioned 
+
 ## Possible solutions
 
+object is locked
+-> check object lock via a HeadObject, if it’s Governance, you can bypass it with a delete object with the header “x-amz-bypass-governance-retention”, also specify the VersionId since a bucket with lock enabled is versioned.
+
+bucket is versioned
+A DeleteObject on a versioned bucket with no VersionId specified will create a delete marker and the objects will still exist. To actually delete it, list all the versions with a ListObjectVersions (you can specify the name of your object as prefix) and then send a DeleteObject on each versions.
